ASoC: samsung: lowland: Split Line Out jack kcontrol from Headphone

Browse source 
This driver has correctly mapped jack kcontrols for Headphone and
Headset Mic. However, it is also mapping Line Out jack detection events
to the Headphone kcontrol.

The WM5100 codec used here can distinguish Line Out connections from
Headphone connections. Decouple the two, expose Line Out to userspace as
an independent kcontrol and add the necessary widget.
