Gwendal Grignou 81d269dc00 common: lightbar: Add histeresis to prevent flickering ...

When ALS is enabled, if light is around one threshold (say 40 lux),
the lightbar will flicker between readings.
Add a histeresis to prevent the flickering.
The current setting is:

setting    ^
(dim)    2 | ------+---->---+
         1 |       +----<---+--->---+
(bright) 0 |                +---<---+---------
           +-------+--------+-------+--------> lux
               20       40      60

BRANCH=smaug
BUG=chrome-os-partner:44400
TEST=check in a dark room (30~40 lux) there is no flickering.
Add unit test.
