[0/6] PCI: dwc: rcar-gen4: Add R-Car V4H support

Message

The pcie-rcar-gen4 driver can reuse other R-Car Gen4 support. However,
some initializing settings differs between R-Car S4-8 (r8a779f0) and
others. The R-Car S4-8 will be minority about the setting way. So,
R-Car V4H will be majority and this is generic initialization way
as "renesas,rcar-gen4-pcie{-ep}" compatible. For now, I tested
both R-Car S4-8 and R-Car V4H on this driver. I'll support one more
other SoC (R-Car V4M) in the future.
