mmc: dcache: allocate cache aligned buffer for scr and switch_status
Currently the sd_change_freq function allocates two buffers on the
stack that it passes down to the MMC device driver. These buffers
could be unaligned to the L1 dcache line size. This causes problems
when using DMA and with caches enabled.
This patch correctly cache alignes the buffers used for reading the
scr register and switch status values from an MMC device.
