Subject: [PATCH 1/1] ASoC: fsl_asrc: use dma_transfer_direction enum when calling dmaengine_prep_dma_cyclic

When fsl_asrc_dma_prepare_and_submit() calls
dmaengine_prep_dma_cyclic(), it uses either DMA_TO_DEVICE or
DMA_FROM_DEVICE. These values are both items of dma_data_direction enum,
not of dma_data_direction enum, which is the type expected by
dmaengine_prep_dma_cyclic().

Replace DMA_TO_DEVICE with DMA_MEM_TO_DEV and DMA_FROM_DEVICE with
DMA_DEV_TO_MEM to fix this type mismatch issue.
