ASoC: wcd9xxx: Setup internal micbias for headset detection 



If recording is also using internal micbias, then after recording
ends, the dapm widget power down callback will reset the state of
internal micbias in codec register. To avoid such issues make sure
internal micbias is setup whenever detection occurs.
