Subject: [PATCH RFC 5/7] ASoC: tlv320aic26: hw_params was unintentionally clearing AIC26 master mode

Commit: 5b0959d472c2 "ASoC: tlv320aic26: Use snd_soc_update_bits()" broke setting AIC26_REG_AUDIO_CTRL3
in master mode when fsref happens to be 48000. The master mode bit was getting cleared.

Also fix setting AIC26_REG_DAC_GAIN and AIC26_REG_AUDIO_CTRL2 which was broke by same commit.

Fixes: 5b0959d472c2 "ASoC: tlv320aic26: Use snd_soc_update_bits()"
