USB: move PCI HCD resume routine

This patch (as1384) moves the resume_common() routine in hcd-pci.c a
little higher in the source file to avoid forward references in an
upcoming patch.  It also replaces the "hibernated" argument with a
more general "event" argument, which will be useful when the routine
is called during a runtime resume.
