I know you like dma, but may I have the compatible etc first in the
nodes? Perhaps move #dma-cells down by the other dma- properties?

I don't think it's nice to keep gpi_dma0 enabled and gpi_dma1 disabled.
Either we do both enabled in sdm845.dtsi or we do both disabled and rely
on the boards to enable what they need.
