[PATCH v1 4/4] arm64: dts: qcom: sa8775p: Add qref and refgen supply for PCIe PHYs

[Ziyue Zhang]

The QMP PCIe PHYs on SA8775p require dedicated qref and refgen voltage
supplies for stable operation. Without these supplies, the system may
occasionally crash.

Add vdda-qref-supply and vdda-refgen-supply in the board files
(Lemans-EVK, Lemans-RIDE, QCS9100-RIDE and QCS9100-RIDE-R3).

Fixes: 94d7d37f6ac3 ("arm64: dts: qcom: lemans-evk: Enable PCIe support")
Fixes: 76326da895b8 ("arm64: dts: qcom: lemans: Refactor ride/ride-r3 boards based on daughter cards")
