irqdomain: Mark fwnodes when their irqdomain is added/removed
This allows fw_devlink to recognize irqdomain drivers that don't use the device-driver model to initialize the device. fw_devlink will use this information to make sure consumers of such irqdomain aren't indefinitely blocked from probing, waiting for the irqdomain device to appear and bind to a driver.
