Add DMA support for RZ/T2H RSPI

Merge series from Cosmin Tanislav <cosmin-gabriel.tanislav.xa@renesas.com>:

The DMA controller can be used to transfer data to and from the SPI
controller without involving the CPU for each word of a SPI transfer.

Add support for DMA mode, and do some other cleanups while touching the
same code.
