Log message:
Clear the DMA select bits in case we use PIO instead of DMA. Some
SDHC controllers get confused if the ADMA bit is set even though we
don't set the DMA enable flag. This can happen with the SDIO stack
which uses PIO for 4 byte read/writes but DMA for larger transfers
and thus switches from one mode to the other.
