Currently, when assign_irq_vector is called and the irq connected in the simulator, the irq is not ready. request_irq will return ENOSYS immediately. It is because the irq chip is unset. Hence set the chip properly to irq_type_hp_sim. And make sure this is done from both users of simulated interrupts. Also we have to set handler here, otherwise we end up in handle_bad_int resulting in spam in logs and no irqs handled. We use handle_simple_irq as these are SW interrupts that need no ACK or anything.
