Implement get_attr() method and use the address width property to report
the IOMMU_ATTR_MAX_IOVA attribute.
Nit: get_attr() method was already implemented in patch #6.
Maybe just "Use address width property to report IOMMU_ATTR_MAX_IOVA attribute"?
Yeap, makes sense.
I would merge with the previous patch also.
Thanks.
