Quentin Schulz c31f51d502 led: remove coloured_LED_init, yellow and blue status LEDs in legacy API
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.
