Upstream commit 631bc8f0134a ("ASoC: sgtl5000: Fix of unmute outputs on probe"), which is e9f621efaebd in v5.3 replaced snd_soc_component_write with snd_soc_component_update_bits and therefore no longer cleared the MUTE_ADC flag. This caused the ADC to stay muted and recording doesn't work any longer. This patch fixes this problem by adding a Switch control for MUTE_ADC.

commit 694b14554d75 ("ASoC: sgtl5000: add ADC mute control") upstream

This control mute/unmute the ADC input of SGTL5000 using its CHIP_ANA_CTRL register.
