Randall Spangler fcd0f0a5e4 link: Hibernate EC when battery level drops below 2% ...

We already shut down the main processor below 3%.  Hibernating the EC
below 2% will further cut power draw and minimize the risk of
deep-discharging the battery.

BUG=chrome-os-partner:14839
BRANCH=link
TEST=manual

1) discharge battery below 3%; system should shut down.  when powered
on again it should shut back down within ~10 sec.

2) discharge battery below 2%; when system shuts down it should also hibernate.

(I've also tested this with a hacked smart_battery.c which lies about
the battery state of charge, since that's faster than waiting for my
battery to discharge.)
