The last user of coloured_LED_init has been recently removed, so we can remove all places it's called and defined as it does nothing now. Nobody makes use of the yellow and blue status LEDs from the legacy API, so let's remove all references to it. Signed-off-by: Quentin Schulz <quentin.schulz@cherry.de>
