[PATCH AUTOSEL 5.2 007/185] ASoC: sgtl5000: Fix of unmute outputs on probe

[Sasha Levin]

From: Oleksandr Suvorov <oleksandr.suvorov@xxxxxxxxxxx>

[ Upstream commit 631bc8f0134ae9620d86a96b8c5f9445d91a2dca ]

To enable "zero cross detect" for ADC/HP, change
HP_ZCD_EN/ADC_ZCD_EN bits only instead of writing the whole
CHIP_ANA_CTRL register.
