nb/intel/haswell;sb/intel/lynxpoint: Enable VT-d and X2APIC
We use the usual static addresses 0xfed90000/0xfed91000 for the GFX IOMMU and the general IOMMU respectively. These addresses have to be configured in MCHBAR registers and reserved from the OS. GFXVTBAR/VTVC0BAR policy registers set to be consistent with proprietary vendor firmwares on hardware of same platform (2 different vendor firmwares compared, found to be identical).
