imx233: two minor fixes for sd/mmc

Browse source 
Always enable support for SET_BLOCK_COUNT on mmc: it is mandatory. For some
reason (probably a mistake) it was disabled unconditionaly on mmc.
Also deselect sd card after init. Although it is unlikely to make a difference,
it is already done for mmc so stay consistent.
