Previously we skipped this for display devices, but ACPI rev 5.0, sec 6.2.7 and 6.2.8 have no requirement to skip them. Remove the check so we configure display devices the same way we configure other devices. See also ac81860ea073 ("PCI: hotplug: pciehp: Removed check for hotplug of display devices").
