dt-bindings: mfd: mediatek: Add codec property for MT6357 PMIC 



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.
