The RK809 MFD provides a RK817 compatible audio codec, supported by the
rk817_codec driver.
This has been already in use by several boards: rk3566-quartz64-b,
k3566-roc-pc, rk3568-evb1-v10, rk3568-lubancat-2, rk3568-odroid-m1,
rk3568-rock-3a. However, dtbs_check fails for all of them:
DTC_CHK arch/arm64/boot/dts/rockchip/rk3568-rock-3a.dtb
rk3568-rock-3a.dtb: pmic@20: '#sound-dai-cells', 'assigned-clock-parents', 'assigned-clocks', 'clock-names', 'clocks', 'codec' do not match any of the regexes: 'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/mfd/rockchip,rk809.yaml#
Document the missing audio codec properties as found on the
rockchip,rk817 schema.
