Since we now have a generic data structure to express an interrupt specifier, convert all hierarchical irqchips that are OF based to use a fwnode_handle as part of their alloc and xlate (which becomes translate) callbacks.As most of these drivers have dependencies (they exchange IRQ specifiers), change them all in a single, massive patch...

Hmm, here removes the of_node, but I think we still need to convert it in the first patch, or will break the git bisect.
