spi: spi-qcom-qspi: Add mem_ops to avoid PIO for badly sized reads 
In the patch ("spi: spi-qcom-qspi: Fallback to PIO for xfers that
aren't multiples of 4 bytes") we detect reads that we can't handle
properly and fallback to PIO mode. While that's correct behavior, we
can do better by adding "spi_controller_mem_ops" for our
controller. Once we do this then the caller will give us a transfer
that's a multiple of 4-bytes so we can DMA.

Fixes: b5762d9560 ("spi: spi-qcom-qspi: Add DMA mode support")
