[AGPGART] intel_agp: restore graphics device's pci space early in resume

Browse source 
Currently in resuming path graphics device's pci space restore is
behind host bridge, so resume function wrongly accesses graphics
device's space. This makes resuming failure which crashed X.
here's a patch to restore device's pci space early, which makes
resuming ok with X.
