Subject: [PATCH 3/3] ARM: at91/dt: add minimal sama5d2 Xplained board

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.
