PCI: Propagate the "ignore hotplug" setting to parent
[ Upstream commit 0824965140fff1bf640a987dc790d1594a8e0699 ] Refine the mechanism introduced by commit f244d8b623da ("ACPIPHP / radeon / nouveau: Fix VGA switcheroo problem related to hotplug") to propagate the ignore_hotplug setting of the device to its parent bridge in case hotplug notifications related to the graphics adapter switching are given for the bridge rather than for the device itself (they need to be ignored in both cases).
