intel-iommu: set iommu_superpage on VM domains to lowest common denominator
commit 8140a95d228efbcd64d84150e794761a32463947 upstream.
set dmar->iommu_superpage field to the smallest common denominator
of super page sizes supported by all active VT-d engines. Initialize
this field in intel_iommu_domain_init() API so intel_iommu_map() API
will be able to use iommu_superpage field to determine the appropriate
super page size to use.
