ASoC: Intel: bytcr_wm5102: Map missing Line Out jack kcontrol

Commit ecd77d49 ("ASoC: Intel: bytcr_wm5102: Add jack detect
support") 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 WM5102 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.
