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.
