vfio: Type1 IOMMU implementation
This VFIO IOMMU backend is designed primarily for AMD-Vi and Intel
VT-d hardware, but is potentially usable by anything supporting
similar mapping functionality. We arbitrarily call this a Type1
backend for lack of a better name. This backend has no IOVA
or host memory mapping restrictions for the user and is optimized
for relatively static mappings. Mapped areas are pinned into system
memory.
