[U-Boot] [PATCH v2] ARM: atmel: add sama5d4 xplained ultra board support

The code for this board supports following features: - Boot media support: NAND flash/SD card/SPI flash - Support LCD display (optional, disabled by default) - Support ethernet - Support USB mass storage

Signed-off-by: Bo Shen voice.shen@atmel.com --- This patch based on the patch to add sama5d4ek board support.

Changes in v2: - Select CPU_V7 in Kconfig
