This is on Lorenzo's pci/rcar branch and headed to -next.

There's a similar older commit on that branch, 2de82ec86674
("dt-bindings: pci: rcar-pci-ep: Document r8a774a1 and r8a774b1") that
came with a companion that added device IDs to pci_endpoint_test.c:
cfb824ddd1c0 ("misc: pci_endpoint_test: Add Device ID for RZ/G2M and
RZ/G2N PCIe controllers").

Is there, or should there be a similar device ID patch for
renesas,r8a774e1-pcie-ep?
