commit 057efcf9faea4769cf1020677d93d040db9b23f3 upstream.
MIC BIAS Internal1 is broken at the moment because we always enable the internal rbias resistor to the TX2 line (connected to the headset microphone), rather than enabling the resistor connected to TX1.
Move the RBIAS code to pm8916_wcd_analog_enable_micbias_int1/2() to fix this.
