Subject: Enable power manager ALS support

Note: the light sensor values on my device seem wrong
(it's only reading 225 or 320 Lux in direct sunlight)
The values in this change are calibrated to do the best we can with those values.
This will need to change when the hardware gets better light sensor.

Bug: 5043500
