description:
begin to make rock64 audio work.

- set status for "analog_sound" to enabled.
- add clocks for the i2s and spdif nodes.
- match "rockchip,rk3066-i2s", "rockchip,rk3188-i2s",
  and "rockchip,rk3288-i2s".

this gets i2s and ausoc to attach, but no audio(4) yet.

to complete this probably also needs a codec driver (appears
to be rk3328 specific, unlike eg pinebookpro's es8316), and
support for "audio-graph-card" type sound cards.
