Axel Lin b4f89a0cce ASoC: msm8916-wcd-analog: Update correct register setting for MIC BIAS Internal1 
pm8916_wcd_analog_enable_micbias_int1() should set micbias1_cap_mode
rather than micbias2_cap_mode.

Also change the order of pm8916_wcd_analog_enable_micbias_int1/init2
functions for better readability.
