userspace works just fine without it because it already knows how to use
bl_power for turning off the display.
- Added brightness-levels to trogdor as well, now the dts is upstream.

Some displays need the low end of the curve cropped in order to make
them happy. In that case we still want to have the 0% point, even though
anything between 0% and 5%(example) would be skipped.

o this conditionally because it seems some devices like to
have the scale inverted:
% git grep "brightness-levels\s*=\s*<\s*[1-9]"|cat
arch/arm/boot/dts/tegra124-apalis-eval.dts: brightness-levels =
<255 231 223 207 191 159 127 0>;
