configs: lahaina: Move ADC2_BCS disable to device mixer paths

Headset SVA detection doesn't work during barge-in use case
due to TX port is muted. This is caused by "ADC2_BCS disable"
mixer path control is not set during device enabling. Move
this mixer path control to "listen-ape-headset-mic" and remove
them from other usecase enabling locations.
