Merge branch 'pci/taku-prt-cleanup' into next

* pci/taku-prt-cleanup:
  PCI/ACPI: Request _OSC control before scanning PCI root bus
  PCI: Don't pass pci_dev to pci_ext_cfg_avail()
  PCI/ACPI: Add _PRT interrupt routing info before enumerating devices
  ACPI: Pass segment/bus to _PRT add/del so they don't depend on pci_bus
