HACK: soc: mediatek: mt8195: make audio's power domain always-on
requested to merge mediatek/aiot/team-baylibre/linux:aouledameur/i1200-k5.15-fix-dmic-hang into mtk-v5.15-dev
DMIC hangs during suspend-to-ram (S3) if audio is recorded. The cause is still being investigated.
To avoid the hang, keep the audio's power domain always-on, this will prevent power/context loss on the audio device.
This is a pure HACK and a proper fix should be introduced to fix DMIC and no longer use always-on flag.
