env: mmc/fat/ext4: make sure that the MMC sub-system is initialized before using it
When booting from a non-MMC device, the MMC sub-system may not be
initialized when the environment is first accessed.
We need to make sure that the MMC sub-system is ready in even a non-MMC
boot case.
Therefore, initialize mmc before loading environment from it.
