atlas: update ALS scale factor
this fixes the ALS reading scale factor so we actually get a decent
range of values based on ambient light intensity. this scale factor
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
