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.
