ASoC: msm8916-wcd-analog: Fix MIC BIAS Internal1

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.
