[PATCH v2 2/3] ARM: dts: rockchip: veyron: Remove 0 point from brightness-levels

[Alexandru Stan]

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 don't need the 0% point, userspace seems to handle this just fine
because it uses the bl_power property to turn off the display.
