[PATCH v3 0/6] PCI: dwc: rcar-gen4: Add support for R-Car X5H PCIe4

Add support for R8A78000 (R-Car X5H) PCIe4.

This driver previously supported R-Car Gen4 S4/V4H/V4M. PCIe features
of R-Car X5H PCIe4 are almost all the same, except for different PHY
which has its own driver, slightly different initialization code and
the DMA is no longer eDMA but HDMA.

Endpoint mode is currently not implemented for R-Car Gen5 PCIe4.
