flashlight: allow to get simple flashlight enable and disable values from deviceinfo

the value for enable/disable for simple sysfs might not always be 0 or 1. one example is the FLX1 phone.
allow to override using deviceinfo and fallback to SIMPLE_ENABLE and SIMPLE_DISABLE if built without deviceinfo or no value is provided
