When requesting an interrupt, we correctly call into the runtime PM framework to guarantee that the underlying interrupt controller is up and running. However, we fail to do so for chained interrupt controllers, as the mux interrupt is not requested along the same path. Augment __irq_do_set_handler() to call into the runtime PM code in this case, making sure the PM flow is the same for all interrupts.
