ASoC: samsung: littlemill: Map missing jack kcontrols

Browse Source 
This driver does not properly map jack pins to kcontrols that PulseAudio
and PipeWire need to handle jack detection events. The WM8958 codec used
here can detect Headphone and Headset Mic connections. Expose each to
userspace as a kcontrol and add the necessary widgets.
