My vote is a tag of "rcar" for the pcie-rcar driver because almost all
new drivers are PCIe, and none of the others use "pcie-" in the tag.

For pci-rcar-gen2.c, we could use "rcar-gen2" (already used by the
last 5 commits, last touched over two years ago).  It's slightly
confusing to use "gen2" to refer to some internal R-Car thing instead
of PCIe Gen 2, so we could use something like "rcar-pci", but I'm not
sure it's worth it.
