[0/7] Enable spi dma on Rockchip RK3399

Hi all,

The first three patches in this series enable spi dma on rk3399,
while the remaining patches are meant to be decreasingly obvious
cleanups to the rockchip spi driver.

Unfortunately I only have rk3399-gru-kevin hardware to test
this on, so it would be nice if someone would test this on
other rockchips.
