[1/2] dt-bindings: PCI: rcar-pci-host: add optional regulators
Commit Message
Support regulators found on the e.g. KingFisher board for miniPCIe and
add a 12v regulator while we are here.

Changes since RFC:
* added 12V supply for completeness
* use PCIe slot in the example instead of miniPCIe because that is what
the Koelsch board offers (just without the regulators ;))

Same for e.g. Salvator-XS.
