Just to help clarify (I could be mistaken as well): is'nt the
interrupt map for user interrupt map nodes that refer to this
interrupt controller node to state they dont need a parent address
specifier - so are we claiming none of the users will have an
interrupt-map (now and never in the future as well) - we we might want
to explain why we think that is the case, and if we are expecting dtc
to deduce that (if so how?)?
