Update the qcom,pcie-common.yaml to include the phys, phy-names properties in the root port node. There is already reset-gpios defined for PERST# in pci-bus-common.yaml, start using that property instead of perst-gpio. For backward compatibility, do not remove any existing properties in the bridge node. Hence mark them as 'deprecated'.
