DTs with new GIC variants which are implementations of the standard
rather than extensions of existing implementations.

However, DTs using these should also state exactly what variant they
are, and those strings should be documented (even if not supported
directly by the driver). It would be nice to have that mentioned in the
commit message.

Otherwise:
