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.
