Extend the driver to make use of iommu_device_register()/unregister()
functions together with iommu_device_set_ops() and iommu_set_fwnode().
These used to be part of the earlier posted 64-bit ARM (r8a7795) series but
it turns out that these days they are required on 32-bit ARM

The 32-bit ARM code gets updated to make use of ->of_xlate() and the
code is shared between 64-bit and 32-bit ARM. The of_device_is_available()
check gets dropped since it is included in of_iommu_xlate().

different kinds of IPMMU hardware. Add use_ns_alias_offset
