After the "PWM backlight interpolation adjustments" patches, the
backlight interpolation works a little differently. The way these
dts files were working before was relying on a bug (IMHO).
Remove the 0-3 range since otherwise we would have a 252 long
interpolation that would slowly go between 0 and 3, looking really bad
in userspace.
We'll still have the 0% point available to userspace, "backlight:
pwm_bl: Artificially add 0% during interpolation" takes care of that.
