[PATCH v12 04/13] iommu: Add a domain attribute to get/set a pagetable configuration

[Jordan Crouse]

Add domain attribute DOMAIN_ATTR_PGTABLE_CFG. This will be used by
arm-smmu to share the current pagetable configuration with the
leaf driver and to allow the leaf driver to set up a new pagetable
configuration under certain circumstances.
