[PATCH 15/16] 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

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]
