dt-bindings: PCI: renesas,r9a08g045-pcie: Add RZ/V2N support
Document the Renesas RZ/V2N PCIe host controller, which is compatible with
the RZ/G3E PCIe IP and therefore uses it as a fallback compatible. The
only difference is that it uses device ID 0x003B.
Make the binding title generic to avoid extending the title for each new
SoC, and update the description to list the supported SoCs and their
capabilities.
