spi/s3c64xx: use correct dma_transfer_direction type
There is a subtle difference between dma_transfer_direction and
dma_data_direction: the former is used by the dmaengine framework,
while the latter is used by the dma-mapping API. Although the
purpose is comparable, the actual values are different and must
not be mixed. In this case, the driver just wants to use
dma_transfer_direction.
Without this patch, building s3c6400_defconfig results in:
drivers/spi/spi-s3c64xx.c: In function 's3c64xx_spi_dmacb':
drivers/spi/spi-s3c64xx.c:239:21: warning: comparison between
'enum dma_data_direction' and 'enum dma_transfer_direction' [-Wenum-compare]
As pointed out by Kukjin Kim, this also changes the use of constants
from DMA_FROM_DEVICE/DMA_TO_DEVICE to DMA_DEV_TO_MEM/DMA_MEM_TO_DEV.
