Subject: [PATCH] ASoC: sgtl5000: Revert "ASoC: sgtl5000: Fix of unmute outputs
 on probe"

This reverts commit 631bc8f0134ae9620d86a96b8c5f9445d91a2dca.

In commit 631bc8f0134a, snd_soc_component_update_bits is used instead of
snd_soc_component_write. Although EN_HP_ZCD and EN_ADC_ZCD are enabled
in ANA_CTRL register, MUTE_LO, MUTE_HP and MUTE_ADC bits are remained as
the default value. It causes LO, HP and ADC are all muted after driver
probe.

The patch is to revert this commit, snd_soc_component_write is still
used and MUTE_LO, MUTE_HP and MUTE_ADC are set as zero (unmuted).
