Add ALS driver for light sensors connected to EC
This adds the driver and a console command to read an Intersil ISL29305
light sensor connected to the EC.
BUG=chrome-os-partner:23380
BRANCH=samus
TEST=manual
Run the "als" command from the EC console, while pointing the sensor in
various directions. It should give higher numbers when facing a light
source. If you get "Error 1", it means the ALS isn't powered.
