Add sama5d3 Xplained board support which use Atmel SAMA5D36 SoC. Now it supports boot from NAND flash and SD/MMC card. Features support: - NAND flash - SD/MMC card - Two USB hosts - Ethernet (one GMAC, one EMAC) Signed-off-by: Bo Shen <voice.shen@atmel.com> [reorder boards.cfg] Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
