mmc: enable CMD23 for multi-block transfers
Enable the support for the CMD23 (SET_BLOCK_COUNT) command to
manage multi-block read/write operations. This allows the MMC
core to use CMD23 in preference to the legacy CMD18/CMD25 plus
CMD12 sequence, reducing command overhead and improving I/O
performance on multi-block transfers.
