Rockchip RK809 shares the same audio codec as the rk817 mfd, it is also
using the same rk817_codec driver. However it is missing from the
bindings.
Update dt-binding documentation for rk809 to include the audio codec
properties. This fixes the following warning from dtb check:
pmic@20: '#sound-dai-cells', 'assigned-clock-parents', 'assigned-clocks',
'clock-names', 'clocks', 'codec' do not match any of the regexes:
'pinctrl-[0-9]+'
