* Fixes touch on some devices like chiron/sagit
* Some other devices (e.g. most MTK) need this because their kernel driver
implementations do not perform as expected (initial unblank is only
happening when altering the panel brightness x -> 0 -> y). In regular
Android, that "unblanking" is done on boot when the lights HAL loads and
sets the initial brightness.
