ARM: at91: sama5: move the sd/mmc env config to at91-sama5_common.h
As almost all sama5 sd/mmc env configurations are same, so move them to
at91-sama5_common.h.
Also define CONFIG_ENV_VARS_UBOOT_CONFIG to have the varaible: $board_name.
Then we can use 'at91-${board_name}.dtb' as the dtb name.
TODO: since sama5d3xek has different dtb name, we need to some extra
stuff to make it work on sama5d3xek boards.
