mmc: block: add fixup of broken CMD23 for Sandisk card

Browse source

Some Sandisk cards(such as "SDMB-32" and "SDM032" cards)
can't support CMD23, and would generate CMD timeout. So add
FIX-UP for these two types Sandisk cards.

Error log:
mmcblk0: timed out sending SET_BLOCK_COUNT command, card status 0x400900
mmcblk0: timed out sending SET_BLOCK_COUNT command, card status 0x400900
mmcblk0: timed out sending SET_BLOCK_COUNT command, card status 0x400900
end_request: I/O error, dev mmcblk0, sector 0
Buffer I/O error on device mmcblk0, logical block 0
mmcblk0: timed out sending SET_BLOCK_COUNT command, card status 0x400900
