ASoC: rk3399-gru-sound: Map missing Line Out jack kcontrol

Commit d0508b4f1604 ("ASoC: rk3399_gru_sound: Add DAPM pins, kcontrols
for jack detection") maps kcontrols for Headphones and Headset Mic jacks
for this driver so that PulseAudio and PipeWire can handle insertion
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 widget.
