[PATCH] spi: spi-fsl-dspi: Free DMA memory with matching function

Driver allocates DMA memory with dma_alloc_coherent() but frees it with dma_unmap_single(). This causes DMA warning during system shutdown (with DMA debugging) on Toradex Colibri VF50 module: WARNING: CPU: 0 PID: 1 at ../kernel/dma/debug.c:1036 check_unmap+0x3fc/0xb04 DMA-API: fsl-edma 40
