sensors: Return a calculated lux value instead using the current 8 entry table
The light sensor now uses the lux to current formula in the datasheet,
I = 10 * log(Ev) uA, and multiplies the result by 4 as an attempt
to correct for the glass in front of the sensor.
Also update the config_autoBrightnessLevels table so the auto brightness
change occurs at the same adc values as before (or close for 7.2 lux).

SensorHAL: clear previous light value on enable
Sensor HAL changes to make light sensor value to be reported on
enabling light sensor.
- Ignore the dummy initial value -1 that is pushed by driver
- Set previous light value to -1 on enable

tuna: sensors: add light, proximity, pressure sensors
NOTE:
- light sensor ADC values need to be calibrated.
