irqchip: Convert all alloc/xlate users from of_node to fwnode
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...
