ASoC: sh: Fix dma direction type
dmaengine_prep_slave_single() expects a enum dma_transfer_direction and not a
enum dma_data_direction. Since the integer representations of both DMA_TO_DEVICE
and DMA_MEM_TO_DEV aswell as DMA_FROM_DEVICE and DMA_DEV_TO_MEM have the same
value the code worked fine even though it was using the wrong type.
Fixes the following warnings from sparse:
sound/soc/sh/fsi.c:1307:42: warning: mixing different enum types
sound/soc/sh/fsi.c:1307:42: int enum dma_data_direction versus
sound/soc/sh/fsi.c:1307:42: int enum dma_transfer_direction
