Let's start to keep the uniform convention, i.e.
led-controller for the LED controller node:

s/leds@30/led-controller@30/

s/an30259a:red:notification/red:notification/

Let's drop devicename section from label, and make it a LED class
driver responsibility to prepend the label with devicename when
composing LED class device name.
