ASoC: wcd: Remove non-essential current source votings from adc



Zdet current source is enabled for 4 pole aux cable and kept
even after plug removal. This increases voltage for both hph left and
right which causes error in cross-connection detection for subsequent plug
detections. Remove current source enablement from unrequired places.
