Add support for allocating private address space instances. Targets that
support per-context pagetables should implement their own function to
allocate private address spaces.
The default will return a pointer to the global address space.

Use the aperture settings from the IOMMU domain to set up the virtual
address range for the GPU. This allows us to transparently deal with
IOMMU side features (like split pagetables).
