Add the audio codec sub-device. This sub-device is used to set the
optional voltage values according to the hardware.
The properties are:
- Setup of microphone bias voltage.
- Setup of the speaker pin pull-down.
Also, add the audio power supply property which is dedicated for
the audio codec sub-device.
