Move the 'generic' version of freertos_risc_v_chip_specific_extensions.h back to a sub-directory as having it in the RISC-V port's base directory was causing SoftConsole to pick up the wrong version (for an unknown reason).

Add a project for the Vega board's RI5CY core.

+ * How to setup clock using clock driver functions:

+ * 1. Call CLOCK_InitXXX() to configure corresponding SCG clock source.
+ *    Note: The clock could not be set when it is being used as system clock.
+ *    In default out of reset, the CPU is clocked from FIRC(IRC48M),
+ *    so before setting FIRC, change to use another avaliable clock source.
+ *
+ * 2. Call CLOCK_SetXtal0Freq() to set XTAL0 frequency based on board settings.
+ *
+ * 3. Call CLOCK_SetXxxModeSysClkConfig() to set SCG mode for Xxx run mode.
+ *    Wait until the system clock source is changed to target source.
+ *
+ * 4. If power mode change is needed, call SMC_SetPowerModeProtection() to allow
+ *    corresponding power mode and SMC_SetPowerModeXxx() to change to Xxx mode.
+ *    Supported run mode and clock restrictions could be found in Reference Manual.

+Overview
+========
+The Hello World demo application provides a sanity check for the new SDK build environments and board bring up. The Hello
+World demo prints the "Hello World" string to the terminal using the SDK UART drivers. The purpose of this demo is to
+show how to use the UART, and to provide a simple project for debugging and further development.
+
+Toolchain supported
+===================
+- GCC RISC-V Embedded 7.1.1
+- RISC-V Eclipse IDE 4.7.2
+
+Hardware requirements
+=====================
+- Mini/micro USB cable
+- RV32M1-VEGA board
+- Personal Computer
+
+Board settings
+==============
+No special settings are required.
+If download M0+ core project, need to let MCU boot from M0+ core, please follow below steps:
+1. Download blhost.exe from www.nxp.com/kboot.
+2. Connect J8 on board to PC using USB cable.
+3. After PC recognize the USB HID device, go to blhost.exe folder, open command line.
+4. Run command "blhost.exe -u -- flash-erase-all-unsecure", it will erase the flash on chip.
+5. Run command "blhost.exe -u -- flash-program-once 0x84 4 ffffffbf", set FOPT3 to boot from M0+ core.
+
+Prepare the Demo
+================
+1.  Connect a USB cable between the host PC and the OpenSDA USB port on the target board. 
+2.  Open a serial terminal with the following settings:
+    - 115200 baud rate
+    - 8 data bits
+    - No parity
+    - One stop bit
+    - No flow control
+3.  Download the program to the target board.
+4.  Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
+
+Running the demo
+================
+The log below shows the output of the hello world demo in the terminal window:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+hello world.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Customization options

+/******************************************************************************
+ * NOTE 1:  This project provides two demo applications.  A simple blinky
+ * style project, and a more comprehensive test and demo application.  The
+ * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select
+ * between the two.  See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY
+ * in main.c.  This file implements the simply blinky style version.
+ *
+ * NOTE 2:  This file only contains the source code that is specific to the
+ * basic demo.  Generic functions, such FreeRTOS hook functions, and functions
+ * required to configure the hardware are defined in main.c.
+ ******************************************************************************
+ *
+ * main_blinky() creates one queue, and two tasks.  It then starts the
+ * scheduler.
+ *
+ * The Queue Send Task:
+ * The queue send task is implemented by the prvQueueSendTask() function in
+ * this file.  prvQueueSendTask() sits in a loop that causes it to repeatedly
+ * block for 1000 milliseconds, before sending the value 100 to the queue that
+ * was created within main_blinky().  Once the value is sent, the task loops
+ * back around to block for another 1000 milliseconds...and so on.
+ *
+ * The Queue Receive Task:
+ * The queue receive task is implemented by the prvQueueReceiveTask() function
+ * in this file.  prvQueueReceiveTask() sits in a loop where it repeatedly
+ * blocks on attempts to read data from the queue that was created within
+ * main_blinky().  When data is received, the task checks the value of the
+ * data, and if the value equals the expected 100, writes 'Blink' to the UART
+ * (the UART is used in place of the LED to allow easy execution in QEMU).  The
+ * 'block time' parameter passed to the queue receive function specifies that
+ * the task should be held in the Blocked state indefinitely to wait for data to
+ * be available on the queue.  The queue receive task will only leave the
+ * Blocked state when the queue send task writes to the queue.  As the queue
+ * send task writes to the queue every 1000 milliseconds, the queue receive
+ * task leaves the Blocked state every 1000 milliseconds, and therefore toggles
+ * the LED every 200 milliseconds.

+/******************************************************************************
+ * NOTE 1:  This project provides two demo applications.  A simple blinky style
+ * project, and a more comprehensive test and demo application.  The
+ * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select
+ * between the two.  See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY
+ * in main.c.  This file implements the comprehensive test and demo version.
+ *
+ * NOTE 2:  This file only contains the source code that is specific to the
+ * full demo.  Generic functions, such FreeRTOS hook functions, and functions
+ * required to configure the hardware, are defined in main.c.
+ *
+ ******************************************************************************
+ *
+ * main_full() creates all the demo application tasks and software timers, then
+ * starts the scheduler.  The web documentation provides more details of the
+ * standard demo application tasks, which provide no particular functionality,
+ * but do provide a good example of how to use the FreeRTOS API.
+ *
+ * In addition to the standard demo tasks, the following tasks and tests are
+ * defined and/or created within this file:
+ *
+ * "Reg test" tasks - These fill both the core registers with known values, then
+ * check that each register maintains its expected value for the lifetime of the
+ * task.  Each task uses a different set of values.  The reg test tasks execute
+ * with a very low priority, so get preempted very frequently.  A register
+ * containing an unexpected value is indicative of an error in the context
+ * switching mechanism.
+ *
+ * "Check" task - The check executes every three seconds.  It checks that all
+ * the standard demo tasks, and the register check tasks, are not only still
+ * executing, but are executing without reporting any errors.  If the check task
+ * discovers that a task has either stalled, or reported an error, then it
+ * prints an error message to the UART, otherwise it prints "Pass.".
