While at it move PCI hotplug (_E01) handler after PCI tree description to avoid forward reference to to not yet declared methods/devices. PS: Forward 'usage' usualy is fine as long as it's hidden within method, however 'iasl' may print warnings. So be nice to iasl/guest OS and do things in proper order. PS2: Also follow up patches will move some of hotplug code from PCI tree to _E01 and that also requires PCI Device nodes build first, before Scope can reuse that from global context.
