[v3,0/2] HDMI Audio on RK356x/Quartz64 Model A

Message

This enables HDMI audio on Quartz64 Model A, and the RK356x SoC in
general.

i2s0 on the RK356x is connected to HDMI, and only has one DMA. I've
confirmed this with the TRM.

To test this, one needs a video clock, i.e. there is no audio if your
screen is off. The framebuffer console or something else needs to be
running to get audio output.

Changes in v3:
 - rebased onto next-20220610

Changes in v2:
 - reordered nodes in rk356x.dtsi to conform
 - reordered properties in rk356x.dtsi to conform
 - add Michael Riesch's Tested-by to rk356x.dtsi
