Similar to the regulator bindings found in "rockchip-pcie-host.txt", this allows optional regulators to be attached and controlled by the PCIe RC driver. That being said, this driver searches in the DT subnode (the EP node, eg pci@0,0) for the regulator property.
The use of a regulator property in the pcie EP subnode such as "vpcie12v-supply" depends on a pending pullreq to the pci-bus.yaml file at
https://github.com/devicetree-org/dt-schema/pull/54
