iommu: Add IOMMU_DOMAIN_NESTED
Introduce a new domain type for a user I/O page table, which is nested on
top of another user space address represented by a PAGING domain. This
new domain can be allocated by the domain_alloc_user op, and attached to
a device through the existing iommu_attach_device/group() interfaces.
The mappings of a nested domain are managed by user space software, so it
is not necessary to have map/unmap callbacks.
