From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>
This patch adds R-Car Sound support for D3 draak.
One note is that it is using different clock definition style
from ulcb/salvator boards to avoid verbose clocks settings
on rcar_sound node (see ulcb.dtsi rcar_sound::clocks).
cs2000 and ADG are cross connected, and need each other.
ulcb/salvator boards assume drivers are probed cs2000 -> rcar_sound.
This draak board assumes drivers are probed rcar_sound -> cs2000.
