irq: Add irq_set_chained_handler_and_data()
Driver authors seem to get the ordering of irq_set_chained_handler() and irq_set_handler_data() wrong - ordering the former before the latter. This opens a race window where, if there is an interrupt pending, the handler will be called between these two calls, potentially resulting in an oops. Provide a single interface to set both of these together, especially as that's commonly what is required.
