We still need the iommu restore hook to invalidate the entries, so that
API I add there is needed anyway. Who actually saves the code doesn't
really matter at that point. The save hook isn't strictly necessary then
but I guess it should be there for symmetry anyway.

Maybe somebody can offer opinions on other iommus?
