ASoC: dt-bindings: samsung,midas-audio: Add GPIO-based headset jack detection

Browse source

Some Samsung devices that share the midas-audio driver use a GPIO-based
approach to headset jack detection, as opposed to using the built-in
jack detection provided by the wm8994 driver. 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.

Add DT configuration values that allow for describing these setups.
