ASoC: mediatek: mt8186-mt6366-da7219-max98357: Map missing jack kcontrols

Commit 8e986748 ("ASoC: mediatek: mt8186-da7219: Expose individual
headset jack pins") maps kcontrols for Headphone and Headset Mic jacks
for this driver so that PulseAudio and PipeWire can handle jack
detection events for these peripherals.

The DA7219 codec used here can also distinguish between Headphone and
Line Out connections that go into the same physical port. Expose the
latter to userspace as a kcontrol as well and add the necessary widgets.
