arm64: dts: qcom: sc7280: Fix Dmic no sound on villager-r1

Fix the DMIC no sound issue of villager-r1 by using "PP1800_L2C" as the
DMIC power source to match the hardware schematic.

This patch:
   1. set vdd-micb-supply to PP1800_L2C as the MIC Bias voltage regulator.
   2. In audio-routing, set VA DMIC01~VA DMIC03 to use the vdd-micb-supply
      setting.
