These interrupt names don't match the binding you've posted (GPU, MMU,
JOB are upper case here, lower case in the binding). Also EVENT and PWR
are not mentioned in the binding - should they be?

I know there are differences here between kbase's requirements and the
existing upstream bindings (case specifically), but I haven't seen a
binding containing EVENT and PWR before.
