In light of the discussion on "[PATCH v3 4/9] dt-bindings: PCI:
renesas,r9a08g045s33-pcie: Add documentation for the PCIe IP on Renesas
RZ/G3S", this should be "renesas,r9a08g045-pcie", and the device node
should be added to the base r9a08g045.dtsi instead (else everything
has to be duplicated in r9a08g045s{13,17,37}.dtsi).  When support for
the variants without PCIe is added, the pcie node should be deleted
using /delete-node/ in r9a08g045s{11,15,31,35}.dtsi.
