Merge branch 'pci/reset'

- Update slot handling so all ARI functions are treated as being in the
  same slot.  They're all reset by Secondary Bus Reset, but previously
  drivers of ARI functions that appeared to be on a non-zero device weren't
  notified and fatal hardware errors could result (Keith Busch)

- Make sysfs reset_subordinate hotplug safe to avoid spurious hotplug
  events (Keith Busch)

- Consolidate bus iteration across the _lock(), _unlock(), and _trylock()
  functions for pci_bus and pci_slot (Ilpo Järvinen)

- Hide Secondary Bus Reset ('bus') from sysfs reset_methods if masked by
  CXL because it has no effect (Vidya Sagar)
