power: Discard ALS data at resume

Currently, if we suspend at indoor light and resume in
completely dark environment, it takes about 10 seconds
for exponential smoothing algorithm to make powerd know
that we are in complete darkness.

This CL fixes that by discard previos data at resume
as ambient light data before suspend won't be relevant.

BUG=b:138666654
TEST=Unit test. manual test on chromebook.
