PCI: rcar-gen4: Add support for R-Car V4H
Add support for r8a779g0 (R-Car V4H).
This driver previously supported r8a779f0 (R-Car S4-8). PCIe features
of both r8a779f0 and r8a779g0 are almost all the same. For example:
- PCI Express Base Specification Revision 4.0
- Root complex mode and endpoint mode are supported
However, r8a779g0 requires specific firmware to be provided, to
initialize the PHY. Otherwise, the PCIe controller will not work.
[kwilczynski: drop the proprietary firmware conversion comment]
