When is #size-cells used in the interrupt tree at all?

And given the odd behavior of using an interrupt map in an interrupt 
parent that is not the device parent (you're potentially using keys from 
different domains that could clash, be a different sizes, etc), if we 
make any changes in that regard, I'd forbid interrupt maps in interrupt 
controllers with no device children, and thus #address-cells has no 
meaning there.
