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). Change-Id: I121ce0f23dca093c9607ac9447b9263f48507a09
