ASoC: samsung: midas_wm1811: Add GPIO-based headset jack detection
Some Samsung devices that use the midas_wm1811 driver use a GPIO-based
method for detecting whether the headset jack is plugged in, as well as
detecting which headset buttons are 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.
