Add Merisc board support
Merisc is the family name for a range of AVR32-based boards.
The boards are designed to be used in a man-machine interfacing
environment, utilizing a touch-based graphical user interface. They host
a vast range of I/O peripherals as well as a large SDRAM & Flash memory
bank.
