mmc: Fixes block read prepare flow for eMMC

In order to start a multiple block read with pre-defined block count the
host must use the SET_BLOCK_COUNT command (CMD23) immediately preceding
the READ_MULTIPLE_BLOCK (CMD18) command. Otherwise the Device will start
an open-ended multiple block read that can be stopped using the
STOP_TRANSMISSION command.
