Log Message:
fill out more of the linux pci API compat

- implement pcie_get_speed_cap(), pcie_bandwidth_available(), and
  pci_is_root_bus().
- expand "enum pci_bus_speed" to add PCIe 5.x and 6.x speeds.
- add "enum pcie_link_width".
- add defines for PCIE_LCSR_LINKSPEED (PCIe generation) and PCIE_LCSR_NLW
  (negotiated lane width) to pcireg.h
- enable amdgpu_device_get_pcie_info() code now it works.
