[ Upstream commit dadab2d4e3cf708ceba22ecddd94aedfecb39199 ]

If NO_DMA=y:

ERROR: "bad_dma_ops" [drivers/spi/spi-fsl-dspi.ko] undefined!

Add a dependency on HAS_DMA to fix this.

This driver did not use DMA before 4.10, so I think this should be reverted in the 4.4 and 4.9 branches.

I'll revert it for 4.4 and 4.9, thanks Ben!
