extcon: arizona: Support direct microphone measurement via HPDET
With some GPIO control it is possible to detect microphones in a wider range of configurations by directly measuring the microphone impedance when the HPDET method cannot distinguish between the behaviour of the two grounds. Allow a GPIO to be provided in platform data and use it to implement this behaviour.
