[PATCH v3 05/16] iommu: Add DOMAIN_ATTR_PTBASE

[Jordan Crouse]

Add an attribute to return the base address of the pagetable. This is used
by auxiliary domains from arm-smmu to return the address of the pagetable
to the leaf driver so that it can set the appropriate pagetable through
it's own means.
