mmc: pxamci: fix enum type confusion

clang points out several instances of mismatched types in this drivers,
all coming from a single declaration:

drivers/mmc/host/pxamci.c:193:15: error: implicit conversion from enumeration type 'enum dma_transfer_direction' to
      different enumeration type 'enum dma_data_direction' [-Werror,-Wenum-conversion]
                direction = DMA_DEV_TO_MEM;
                          ~ ^~~~~~~~~~~~~~
drivers/mmc/host/pxamci.c:212:62: error: implicit conversion from enumeration type 'enum dma_data_direction' to
      different enumeration type 'enum dma_transfer_direction' [-Werror,-Wenum-conversion]
        tx = dmaengine_prep_slave_sg(chan, data->sg, host->dma_len, direction,

The behavior is correct, so this must be a simply typo from
dma_data_direction and dma_transfer_direction being similarly named
types with a similar purpose.
