The series initially reworks the config space accessors to use the existing pci_ops struct. Then there's removal of various private data that's also present in the pci_host_bridge struct. There's also some duplicated common (PCI and DWC) register defines which I converted to use the common defines. Finally, the initialization for speed/gen, number of lanes, and N_FTS are all moved to the common DWC code. This is compile tested only as I don't have any DWC based h/w, so any testing would be helpful. A branch is here[1].
