Registering an irqdomain sets the flag for the fwnode. But having the
flag set when a device is added is interpreted by fw_devlink to mean the
device has already been initialized and will never probe. This prevents
fw_devlink from creating device links with the gpio_device as a
supplier. So, clear the flag before adding the device.
