Merge branch 'pci/misc' 

- Add NumaChip SPDX header (Krzysztof Wilczynski)

  - Replace EXTRA_CFLAGS with ccflags-y (Krzysztof Wilczynski)

  - Remove unused includes (Krzysztof Wilczynski)

  - Avoid AMD FCH XHCI USB PME# from D0 defect that prevents wakeup on USB
    2.0 or 1.1 connect events (Kai-Heng Feng)

  - Removed unused sysfs attribute groups (Ben Dooks)

  - Remove PTM and ASPM dependencies on PCIEPORTBUS (Bjorn Helgaas)

  - Add PCIe Link Control 2 register field definitions to replace magic
    numbers in AMDGPU and Radeon CIK/SI (Bjorn Helgaas)

  - Fix incorrect Link Control 2 Transmit Margin usage in AMDGPU and Radeon
    CIK/SI PCIe Gen3 link training (Bjorn Helgaas)

  - Use pcie_capability_read_word() instead of pci_read_config_word() in
    AMDGPU and Radeon CIK/SI (Frederick Lawler)
