atlas: update ALS scale factor
atlas: update ALS scale factor

this fixes the ALS reading scale factor so we actually get a decent

still needs to be calibrated, but is a good guess based on nocturne.

BUG=b:112784910,b:112863863
BRANCH=none
TEST="accelinfo on" on EC console now reports sensible readings from
	the ALS
