The Rockchip SPI controller works fine without DMA (aside from a few
warnings).  The DMA property even implies this, saying:

  DMA request names should include "tx" and "rx" if present.

Officially mark the properties as optional.

Applied all, thanks.  Please use subject bindings matching the style for
the subsystem.
