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.
Could you please check these three patches. I may missed to use V3, but still used V2. The three patches are new for the env no.

I have not tested, but they looks fine - I am picking them up before my PR.
