------------------

[ Upstream commit d9be398afb2c3333716324352d062c50112e4e86 ]

When lighting up the segment identifying wireless controller, Instead of
sending command directly to the controller, let's do it via LED API (usinf
led_set_brightness) so that LED object state is in sync with controller
state and we'll light up the correct segment on resume as well.
