This patch introduces the boilerplate for a new hypercall to allow a
domain to control IOMMU mappings for its own pages.
Whilst there is duplication of code between the native and compat entry
points which appears ripe for some form of combination, I think it is
better to maintain the separation as-is because the compat entry point
will necessarily gain complexity in subsequent patches.
NOTE: This hypercall is only implemented for x86 and is currently
restricted by XSM to dom0. Its scope can be expanded in future
if need be.
