poppy: Cut off critically low battery

Browse Source 
Instead of going to hibernate when the battery is critically low
we should cut off power entirely.

Even with the PMIC shut down the H1 chip consumes more power than
is healthy when the battery is already critically low, depleting it
to dangerously low voltage levels faster than it should.

(Reference: https://chromium-review.googlesource.com/582543)

BUG=b:64460667
BRANCH=None
TEST=Manual testing to ensure that EC cuts off battery when it is
critically low instead of hibernating on soraka.
