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 7.26 and
94.5 lux).
