iommu/intel: disable DMAR for g4x integrated gfx
DMAR support on g4x/gm45 integrated gpus seems to be totally busted. So don't bother, but instead disable it by default to allow distros to unconditionally enable DMAR support. v2: Actually wire up the right quirk entry, spotted by Adam Jackson. Note that according to intel marketing materials only g45 and gm45 support DMAR/VT-d. So we have reports for all relevant gen4 pci ids by now. Still, keep all the other gen4 ids in the quirk table in case the marketing stuff confused me again, which would not be the first time.
