AMD/IOMMU: also insert IVMD ranges into Dom0's page tables

So far only one region would be taken care of, if it can be placed in
the exclusion range registers of the IOMMU. Take care of further ranges
as well. Seeing that we've been doing fine without this, make both
insertion and removal best effort only.
