  PCI: pciehp: Ignore belated Presence Detect Changed caused by DPC (2025-06-18 10:10:19 -0500)

----------------------------------------------------------------

- Set up runtime PM even for devices that lack a PM Capability as we did
  before 4d4c10f763d7 ("PCI: Explicitly put devices into D0 when
  initializing"), which broke resume in some VFIO scenarios (Mario
  Limonciello)

- Ignore pciehp Presence Detect Changed events caused by DPC, even if they
  occur after a Data Link Layer State Changed event, to fix a VFIO GPU
  passthrough regression in v6.13 (Lukas Wunner)
