imx233: two minor fixes for sd/mmc
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. Change-Id: I276f0d95f5bb6a0bf431c2fff4589d3dfb15f8c7
