spi: cadence-quadspi: fix dma_unmap_single() call
There are separate constants for the dma-mapping API and the dmaengine
API, mixing them up causes a warning in some builds:
In file included from drivers/spi/spi-cadence-quadspi.c:12:
drivers/spi/spi-cadence-quadspi.c: In function 'cqspi_versal_indirect_read_dma':
drivers/spi/spi-cadence-quadspi.c:950:55: error: implicit conversion from 'enum dma_transfer_direction' to 'enum dma_data_direction' [-Werror=enum-conversion]
950 | dma_unmap_single(dev, dma_addr, bytes_to_dma, DMA_DEV_TO_MEM);
| ^~~~~~~~~~~~~~
include/linux/dma-mapping.h:407:70: note: in definition of macro 'dma_unmap_single'
407 | #define dma_unmap_single(d, a, s, r) dma_unmap_single_attrs(d, a, s, r, 0)
