[PATCH v3 1/6] dt-bindings: PCI: Add bindings for Brcmstb EP voltage regulators

[Jim Quinlan]

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 at 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
