ASoC: tlv320aic32x4: Fix problem with first capture.
In its previous status, the first capture didn't work properly; nothing was actually recorded from the microphone. This behaviour was observed using a Visstrim M10 board. In order to solve this BUG a workaround has been added that, during the initialization process of the codec, powers on and off the ADC. The issue seems related to a HW BUG or some behavior that is not documented in the datasheet.
