Patch 2 also refactors fb_mmc.c to use the new helpers — please
mention the MMC conversion here in v3.

Since you are adding a new feature (the N:partition parser, plus
GPT/MBR flashing on the block backend), please add test coverage. See
test/dm/fastboot.c which already exercises
fastboot_mmc_get_part_info() - you can add cases there for the block
path: a successful '0:foo' parse, the bare 'foo' fallback to the
default device, and rejection of a leading-colon name like ':gpt'.
Otherwise the parser and is_partition_table_name() interaction are
easy to break in future refactors.

BTW the v2 changelog has 'Seperate' (twice) and 'fot' - please tidy this up.

Regards,
Simon
