Some sandisk card can't support CMD23, cmd timeout will generate.
SO add FIX-UP for two type of these Sandisk cards.
"SDMB-32" and "SDM032"
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

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