ARM: vexpress/mps2: introduce MPS2 platform

Browse Source 
The Cortex-M Prototyping System (or V2M-MPS2) is designed for
prototyping and evaluation Cortex-M family of processors including the
latest Cortex-M7

It comes with a range of useful peripherals including 8MB single cycle
SRAM, 16MB PSRAM, Ethernet, QSVGA touch screen panel, 4bit RGB VGA
connector, Audio, SPI and GPIO.

Support for Cortex-M Prototyping System (or V2M-MPS2) which comes
with a range of available cores like Cortex-M3/M4/M7.
Please, note that depends which Application Note is used memory map
for the platform may vary, so adjustment of RAM base might be needed.
