irqchip/irq-imx-gpcv2: Mark fwnode device as not initialized 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.

When the system is in WFI (wait for interrupt) mode, the GPC block will be the first block on the platform to be activated and signaled. In normal wait mode during cpu idle, the system can be woken up by any enabled interrupts. In standby or suspend mode, the system can only be wokem up by the pre-defined wakeup sources.
