Subject: [PATCH v2 6/7] 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()")
