    sh: heartbeat consolidation for banked LEDs.
    
    This consolidates the various board heartbeat LED implementations,
    used for strobing the load average across a LED bank. Those boards
    not implementing a full bank can hook in via the LED class.
    
    We leave the compat hook in the machvec for now until those non-banked
    boards are able to migrate to the drivers/leds.
