From: Jérôme de Bretagne <[email protected]>
Align with the reference implementation from the ThinkPad X13s.
The audio-routing setup specifies two power supplies for each DMIC,
but only one of them can be active at the same time.
Drop the redundant routes to the pull-up "VA MIC BIASn" supplies as
done in commit a2e617f4e698 ("arm64: dts: qcom: sc8280xp-x13s: Drop
duplicate DMIC supplies").
There is no functional difference except that we skip briefly switching
to pull-up mode when shutting down the microphone.
