I like this idea (a 'leds' parent node).  They aren't really children
of the GPIO node or any other device/bus in the system.  Putting them
under a dedicated 'leds' node would make them easy to find and would
have the added advantage of making it easier to have a single driver
instance manage the whole lot.
