[2/2] ASoC: amd: acp3x-5682: Expose individual headset jack pins

Commit Message

The rt5682 codec is able to distinguish between two event types:
headphone insertion/removal and headset microphone insertion/removal.
However, currently, the acp3x-5682 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.

This change is based on commit 194ff8db0378 ("ASoC: mediatek:
mt8192-mt6359: Expose individual headset jack pins").
