[U-Boot] [PATCH V2 1/4] imx: mx7dsabresd: move mmc_get_env_devno to soc code
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.

Changes V2: new patch. mx7dsabresd implemented mmc_get_env_devno. So need to refactor it for patch 2/4

Some boards support booting from different SD card slots. For example, mx6dpsabresd board supports booting from SD2, SD3, EMMC4, using different boot switch. And the index numbers are SD2(0), SD3(1), EMMC4(2). But CONFIG_SYS_MMC_ENV_DEV is hardcoded to 1(for SD3), so when booting from SD2(using 0), uboot complains "MMC: no card present", since there is no card in SD3 slot.
This patch introduces a weak function which still returns CONFIG_SYS_MMC_ENV_DEV to avoid break other boards. Then different boards can implement mmc_get_env_devno to read env from the correct sd/emmc.

Tom sets this patch as deferred - then applying the rest of the series makes no sense. Patchset should be rechecked later after next release.

Implement mmc_get_env_devno, devno can be got from smbr1 of SRC. Introduce a weak function board_mmc_get_env_devno, different boards can implement it according to different sdhc controllers that used by the board.
