ASoC: wcd934x: enable lineout path in codec

Lineout path in codec supports differential output that can be
routed to headphones or speakers. Add required register sequence
changes to enable both the lineout paths on the codec. Either of
the lineouts can be used in mono playback or both can be used for
stereo playback.
