This setup uses two GPIOs (one for jack detection and another for key detection) and an ADC channel for determining the jack type or button pressed.

There are two GPIOs: a "headset detect" GPIO responsible for detecting jack insertion, and a "headset key" GPIO which triggers when a button on the headset is pressed. The plug type and the button pressed are determined based on information from an ADC channel. The headset mic is enabled by a headset mic bias regulator. Add support for the GPIO-based headset jack detection mechanism, and make it configurable from the device tree. This implementation borrows somewhat from the aries_wm8994.c driver, though there are a few changes to make the code cleaner, and to add support for DT-based configuration. Notably, a dependency on IIO is introduced, to accommodate the ADC reading requirement.

Add the MCLK2 clock to the WM1811 codec clock property to properly describe the hardware.
