Only the basic support for this new Atmel Cortex-A5 SoC. A subset of the
peripherals is setup to allow booting.
IRQ, clocks, USB, sd/mmc, crypto, timers, ethernet and uart/usart peripheral
nodes are added.

To: linux-arm-kernel
Add minimal support for the new sama5d2 Xplained board. Only USB, sd/mmc,
ethernet and uart/usart peripherals added.
With this DTS file you can boot the board and begin to play with it.
Rootfs on NFS and sd card have successfully been tested.
