spi: spi-davinci: Fix direction in dma_map_single()
commit 89c66ee890af18500fa4598db300cc07c267f900 upstream. Commit 048177ce3b3962852fd34a7e04938959271c7e70 (spi: spi-davinci: convert to DMA engine API) introduced a regression: dma_map_single() is called with direction DMA_FROM_DEVICE for rx and for tx.
