Pull up following revision(s) (requested by riastradh in ticket #998):
sys/dev/pci/agp_i810var.h: revision 1.7
sys/external/bsd/drm2/i915drm/intel_gtt.c: revision 1.7
sys/dev/pci/agp_i810.c: revision 1.123
Restore gtt page table control register on resume.
Additional subroutine agp_i810_reset is used by i915drmkms to make
sure it happens early enough, since i915drmkms resumes before agp.
XXX pullup-7
XXX pullup-8
