ata: ep93xx: Use proper enums for directions
Clang warns when one enumerated type is implicitly converted to another.
drivers/ata/pata_ep93xx.c:662:36: warning: implicit conversion from
enumeration type 'enum dma_data_direction' to different enumeration type
'enum dma_transfer_direction' [-Wenum-conversion]
drv_data->dma_rx_data.direction = DMA_FROM_DEVICE;
~ ^~~~~~~~~~~~~~~
drivers/ata/pata_ep93xx.c:670:36: warning: implicit conversion from
enumeration type 'enum dma_data_direction' to different enumeration type

~ ^~~~~~~~~~~~~
drivers/ata/pata_ep93xx.c:681:19: warning: implicit conversion from
enumeration type 'enum dma_data_direction' to different enumeration type

drivers/ata/pata_ep93xx.c:692:19: warning: implicit conversion from
enumeration type 'enum dma_data_direction' to different enumeration type
'enum dma_transfer_direction' [-Wenum-conversion]
conf.direction = DMA_TO_DEVICE;
~ ^~~~~~~~~~~~~
Use the equivalent valued enums from the expected type so that Clang no
longer warns about a conversion.
DMA_TO_DEVICE = DMA_MEM_TO_DEV = 1
DMA_FROM_DEVICE = DMA_DEV_TO_MEM = 2
