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...
