intel-iommu: introduce Intel IOMMU (VT-d) emulation

Browse source

Add support for emulating Intel IOMMU according to the VT-d specification for
the q35 chipset machine. Implement the logics for DMAR (DMA remapping) without
PASID support. The emulation supports register-based invalidation and primary
fault logging.
