[PATCH 1/2] dt-bindings: phy: qcom,ipq8074-qmp-pcie: document IPQ9650 QMP PCIe PHYs

[Kathiravan Thirumoorthy]

Document the single-lane and dual-lane QMP PCIe PHYs found on the
IPQ9650 SoC.

Unlike the PHYs in the other supported IPQ SoCs, the IPQ9650 PHYs require
the on-chip refgen supply to power up. Add the refgen-supply property
and require it only for the IPQ9650 compatibles.
