Merge branch 'pci/enumeration'

- Use pci_find_vsec_capability() instead of open-coding it (Andy
  Shevchenko)

- Convert pci_dev_present() stub from macro to static inline to avoid
  'unused variable' errors (Hans de Goede)

- Convert sysfs slot attributes from default_attrs to default_groups (Greg
  Kroah-Hartman)

- Use DWORD accesses for LTR, L1 SS to avoid BayHub OZ711LV2 erratum (Rajat
  Jain)

- Remove unnecessary initialization of static variables (Longji Guo)

* pci/enumeration:
  x86/PCI: Remove initialization of static variables to false
  PCI: Use DWORD accesses for LTR, L1 SS to avoid erratum
  PCI/sysfs: Use default_groups in kobj_type for slot attrs
  PCI: Convert pci_dev_present() stub to static inline
  PCI: Use pci_find_vsec_capability() when looking for TBT devices
