spi: pic32: Use proper enum in dmaengine_prep_slave_rg
Clang warns when one enumerated type is converted implicitly to another: drivers/spi/spi-pic32.c:323:8: warning: implicit conversion from enumeration type 'enum dma_data_direction' to different enumeration type 'enum dma_transfer_direction' [-Wenum-conversion] DMA_FROM_DEVICE, ^~~~~~~~~~~~~~~ drivers/spi/spi-pic32.c:333:8: warning: implicit conversion from enumeration type 'enum dma_data_direction' to different enumeration type 'enum dma_transfer_direction' [-Wenum-conversion] DMA_TO_DEVICE, ^~~~~~~~~~~~~ 2 warnings generated. Use the proper enums from dma_transfer_direction (DMA_FROM_DEVICE = DMA_DEV_TO_MEM = 2, DMA_TO_DEVICE = DMA_MEM_TO_DEV = 1) to satify Clang.
