Make these configurable via DT. This v4 moves the exponential brightness mode to the back of the series as per Pavel's request: https://lore.kernel.org/linux-next/20200106103233.GA32426@amd/T/#m93270a9bf10b88e060f4e4cf5701c527476de985 The end result is identical and i've tested everything still works when dropping the last to patches and checked compiltion via git rebase -i ... -exec 'make ... Image dtbs' Patches are against linux-leds-next.
