liblight: Kanged mostly from hardware/qcom/sdm845/display/liblight
Removed the LED control paths we dont yet support upstream and
updated backlight wled brightness sysfs path from downstream
"/sys/class/backlight/panel0-backlight/brightness" to upstream
"/sys/class/backlight/wled/brightness".

+ unless required by applicable law (such as deliberate and grossly
+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
