[PATCH] ASoC: mediatek: mt8186: fix DMIC record noise

From: Jiaxin Yu
Date: Sat Aug 20 2022 - 03:19:52 EST


When the first DMIC recording is power down, mtkaif_dmic will be reset.
This will cause configuration error in the second DMIC recording. So do
not reset mtkaif_dmic except in "MTKAIF_DMIC Switch" kcontrol.
