arm64: dts: qcom: sc8280xp-arcata: Drop duplicate DMIC supplies

Browse Source 
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 a2e617f4e6 ("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.
