- Move struct dwc_pcie_vsec_id to include/linux/pcie-dwc.h, where it can be
  shared by debugfs, perf, sysfs, etc (Manivannan Sadhasivam)

- Add dw_pcie_find_vsec_capability() to locate Vendor Specific Extended
  Capabilities (Shradha Todi)

- Add debugfs-based Silicon Debug, Error Injection, Statistical Counter
  support for DWC (Shradha Todi)

- Add debugfs property to expose LTSSM status of DWC PCIe link (Hans Zhang)

- Add Rockchip Vendor ID and Vendor Specific ID of RAS DES Capability so
  the DWC debugfs features work for Rockchip as well (Niklas Cassel)
