Tom Rini 7d08077334 Convert CONFIG_SYS_MMC_ENV_DEV et al to Kconfig
This converts the following to Kconfig:
   CONFIG_SYS_MMC_ENV_DEV
   CONFIG_SYS_MMC_ENV_PART

Note that with this conversion we now have consistent behavior with
respect to ensuring that we have always selected the correct MMC
device and hardware partition.
