Add "renesas,pci-r8a7793" as a compatibility string for
"renesas,pci-rcar-gen2".
This doesn't change the driver, so it does nothing by itself. But it
does mean that checkpatch won't complain about a future patch that adds
"renesas,pci-r8a7793" to a DT, which helps ensure that shipped DTs use
documented compatibility strings.

the values that were previously hardcoded into the driver.
