ASoC: mediatek: mt8186-da7219: Expose individual headset jack pins

Browse source 
The da7219 codec is able to distinguish between two event types:
headphone insertion/removal and headset microphone insertion/removal.
However, currently, the mt8186-da7219 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.
