ASoC: qcom: sc7280: Map missing jack kcontrols

This driver does not properly map jack pins to kcontrols that PulseAudio
and PipeWire need to handle jack detection events. The RT5682 and
RT5682s codecs used here can detect Headphone and Headset Mic
connections. Expose each to userspace as a kcontrol.
