intel-iommu: Decode (and ignore) RHSA entries
I recently got a system where the DMAR table included a couple of RHSA
(remapping hardware static affinity) entries. Rather than printing a
message about an "Unknown DMAR structure," it would probably be more
useful to dump the RHSA structure (as other DMAR structures are dumped).
