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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
