sm7125-common: Add light sensor lcd_onoff node to powerhint

* On stock ROM Samsung uses that node to tell the light sensor if the screen is on or not in order to correct lux values reported by the sensor
* This will prevent our light sensor from reporting way too high lux values when the screen brightness is high and therefore heavily improves auto brightness behaviour
