cmd_mmc.c: Add 'partconf' command to mmc
Add a partconf sub-command to the mmc command to allow for setting
the boot_ack, boot_partition and partition_access fields of
PARTITION_CONFIG (formerly BOOT_CONFIG, EXT_CSD[179]). Part of this
requires changing the check for 'part' from an strncmp to a strcmp, like
the rest of the sub-commands.
