Adds the mmc hwpartition sub-command to perform eMMC hardware
partitioning on an mmc device. The number of arguments can be
large for a complex partitioning, but as the partitioning has
to be done in one go it is difficult to make it simpler.

The eMMC partition write reliability settings are to be set while
partitioning a device, as per the eMMC spec, so changes to these
attributes needs to be done in the hardware partitioning API.
This commit adds such support.
