For the sake of internal consistency, unset maximum brightness of eco
led and make it activatable only on values >= LED_FULL.

Here is a small statistics covering max brightness of platform-x86 leds:
1 other unset
8 6 7
3/7 leds that have unset max_brightness are activated on nonzero value.
The other 4 are fujitsu-laptop leds. Maybe someone from led subsystem
would be willing to look at this and standardise guidelines on how and
when to use different brightness levels. Hopefully, this could then be
reverted.
