cmd: mmc: Allow using partition name in mmc erase command
The mmc erase command currently requires blk# and cnt parameters
which can be obtained using the part start and part size commands
if the entire partition needs to be erased.
Simplify the use of the mmc erase command by allowing the partition
name to be specified directly.
