The irq_domain::dev is used for power management purposes related to the
irq domain. But for irqsteer, the runtime PM has been forbid in order to
workaround other issues. So there is no need to set data->domain->dev.
With this change, the devices which leverage the irqsteer irqchip will
not run into the following call trace when setting up irq handler.
