Leaving microphone bias off is a valid setting and even used in the DT binding document example. Add this setting here and document the same. Although it may not make much sense to enable a microphone here without any bias, it is a valid setting that can be chosen by DT and may be needed for some boards.
If we really want to pay attention to something setting this up we'd need to completely remove the widget - what the code is doing at the minute is setting the voltage that the bias will go to when enabled, there's still a widget for turning it on and off. There's some chance that this will break existing boards.
