Subject: [PATCH v3] arm64: dts: qcom: sc7280: Use "PP1800_L2C" as the DMIC power source.

Use "PP1800_L2C" as the DMIC power source to match the hardware
schematic by:
   1. Set MIC bias voltage regulator (vdd-micb-supply) to PP1800_L2C.
   2. In audio-routing, set VA DMIC01~VA DMIC03 to use the vdd-micb-supply
      setting.

It fixes the DMIC no sound issue of villager-r1.
