The A31 SoC's codec has various inputs, outputs and microphone bias supplies. These can be routed on the board in different ways, such as:
Microphones all use the MBIAS main microphone supply or one mic may use the HBIAS supply, which supports headset detection and buttons.
Line Out may be routed to an audio jack, or an onboard speaker amp with power controls.
Add support for specifying the audio routes in the device tree.
