mmc-utils: Add blockprotect command set
This patch adds a group of commands that allow controlling an eMMC's
user partition write-protect features, which allow temporary, permanent
or until-next-power-on write-protection of a write-protect block (which
is a device-dependent multiple of an erase block).
BUG=None
TEST=Manual enabling, disabling and writing of a bunch of blocks on my
Minnie.
