This series adds Rockchip PCIe V3 support found on rk3568 SOC.

It is based on "Enable rk356x PCIe controller" series of Peter Geis
v9: https://patchwork.kernel.org/project/linux-rockchip/list/?series=636944

Compared to PCIeV2 which uses the Naneng combphy, PCIe v3 uses a dedicated
PCI-phy.

New in this version is that lane-map is no separate patch and moved from
PCIe- to phy-driver.

Peter has tested m2-slot too and so the bifurcation.

The Phy-Patch is now changed to original author, but our changes are
squashed in.
