ASoC: tlv320aic32x4: SND_SOC_DAPM_MICBIAS is deprecated

Browse source 
SND_SOC_DAPM_MICBIAS is deprecated, replace it with SND_SOC_DAPM_SUPPLY.

MICBIAS voltage wasn't supplied to the microphone with the older
SND_SOC_DAPM_MICBIAS widget, hence the microphone wouldn't work.

This patch fixes the problem.
