mmc: mxs-mmc: fix the dma_transfer_direction migration
The commit 05f5799 (mmc-host: move to dma_transfer_direction) left out
the DMA_NONE, in turn breaks the driver as below.
[ 0.650000] mxs-mmc mxs-mmc.0: initialized
[ 0.650000] mxs-mmc mxs-mmc.1: initialized
[ 0.690000] mxs-dma mxs-dma-apbh: maximum bytes for sg entry exceeded: -55906
7475 > 65280
[ 0.690000] mxs-mmc mxs-mmc.0: mxs_mmc_ac: failed to prep dma
