Move mmc_get_env_devno to soc.c Introduce a weak function board_mmc_get_env_devno. Different boards can implement this according to sdhc controller which is used by the board. Signed-off-by: Peng Fan <peng.fan@nxp.com> Cc: Stefano Babic <sbabic@denx.de> --- Changes V2: new patch. mx7dsabresd implemented mmc_get_env_devno.
