mtd: spi-nor: cadence-quadspi: Use proper enum for dma_[un]map_single

Clang warns when one enumerated type is converted implicitly to another.

different enumeration type 'enum dma_data_direction' [-Wenum-conversion]

Use the proper enums from dma_data_direction to satisfy Clang.

DMA_FROM_DEVICE = DMA_DEV_TO_MEM = 2
