Subject: [PATCH v2 1/1] arm64: dts: qcom: x1e80100-lenovo-yoga-slim7x: enable MICs LDO

Particular device comes without headset combo jack, hence does not
feature wcd codec IC. In such cases, DMICs are powered from vreg_l1b.
Describe all 4 microphones in the audio routing. vdd-micb is defined
for lpass-macro already.
