ARM: at91: sama5d3_xplained: save environment in a FAT file in MMC card

This patch will save U-Boot environment as a file: uboot.env, in FAT partition instead of saving it in raw sector of MMC card. This make us easier to manage the environment file. Signed-off-by: Josh Wu <[email protected]> Acked-by: Bo Shen <[email protected]>
