env: mmc: statically set the environment partition name
The new opt-out setting, CONFIG_ENV_MMC_PARTITION, statically sets
the MMC environment partition name. Prior to this patch, the only way
to declare this partition name was by creating a
'u-boot,mmc-env-partition' parameter in the device-tree's /config node.
This setting provides additional flexibility, particularly in cases
where accessing the device-tree is not straightforward (e.g. QEMU).
If undeclared, the device-tree's setting will be used.
