ASoC: mediatek: mt8195: Expose individual headset jack pins
The rt5682 codec is able to distinguish between two event types:
headphone insertion/removal and headset microphone insertion/removal.
However, currently, the mt8195 ASoC driver exposes a single kcontrol
for the headset jack, so userspace isn't able to differentiate between
the two events.
Add a definition for the headset jack pins, so that a separate jack
kcontrol is created for each one, allowing userspace to track and handle
them individually.
