[ Upstream commit d27224a45e5457ad89195d92decdd57596253428 ]
This driver does not map jack pins to kcontrols that PulseAudio/PipeWire need to handle jack detection events. The WM1811 codec used here seems to support detecting Headphone and Headset Mic connections. Expose each to userspace as a kcontrol and add the necessary widgets.
