mmc: block: add eMMC hardware reset support
For cards that support hardware reset (just eMMC), try a reset and retry before returning an I/O error. However this is not done for ECC errors and is never done twice for the same operation type (READ, WRITE, DISCARD, SECURE DISCARD) until that type of operation again succeeds.
