arm64: dts: qcom: trogdor: Add brightness-levels
We want userspace to represent the human perceived brightness.
Since the led drivers and the leds themselves don't have a
linear response to the value we give them in terms of perceived
brightness, we'll bake the curve into the dts.
The panel also doesn't have a good response under 5%, so we'll avoid
sending it anything lower than that.
Note: Ideally this patch should be coupled with the driver change from
"backlight: pwm_bl: Fix interpolation", but it can work without it,
without looking too ugly.
