[PATCH v2 4/4] arm64: dts: qcom: x1e80100-qcp: Add qref supply for PCIe PHYs

[Wenbin Yao]

From: Qiang Yu <quic_qianyu at quicinc.com>

All PCIe PHYs on X1E80100 require vdda-qref power supplies, but this is
missing in the current PHY device tree node. The PCIe port can still
function because the regulator L3J, which vdda-qref consumes, is voted by
other components.

Since the device tree should accurately describe the hardware, add the
vdda-qref power supply explicitly in all PCIe PHY device nodes.
