Add minimal support for the new sama5d2 Xplained board. Only USB, spi/i2c, 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. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
