common/charge_state: Cut off battery if board selects CONFIG_BATTERY_CRITICAL_SHUTDOWN_CUT_OFF

Browse Source 
If board selects both CONFIG_BATTERY_CRITICAL_SHUTDOWN_CUT_OFF and
CONFIG_HIBERNATE, then CONFIG_BATTERY_CRITICAL_SHUTDOWN_CUT_OFF should
be given higher preference when deciding what action to take in case
of critical battery.

This is necessary on boards where components like H1 chip could be
consuming more power than is healthy when the battery is already
critically low, depleting it to dangeriously 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.
