Since this device is only partially initialized by the irqchip driver, we need to mark the fwnode device as not initialized. This is to let fw_devlink know that the device will be completely initialized at a later point. That way, fw_devlink will continue to defer the probe of the power domain consumers till the power domain driver successfully binds to the struct device and completes the initialization of the device.
