Move _GPE block declaration before it gets referenced by other
hotplug handlers. 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.
