irqdomain: Convert irqdomain-%3Eof_node to fwnode
Now that we have everyone accessing the of_node field via the irq_domain_get_of_node accessor, it is pretty easy to swap it for a pointer to a fwnode_handle. This translates into a few limited changes in __irq_domain_add, and an updated irq_domain_get_of_node.
