Adrian Hunter bd788c9665 mmc_block: add discard support 
Enable MMC to service discard requests.  In the case of SD and MMC cards
that do not support trim, discards become erases.  In the case of cards
(MMC) that only allow erases in multiples of erase group size, round to
the nearest completely discarded erase group.
