charger: Change unlocked battery level ignore conditions
x86 systems will auto-power-on when power is applied to the EC. When
the battery level is critically low, power-on is prevented, except when
the system is unlocked. So, when unlocked, some systems will
auto-power-on regardless of battery level, overcurrent the charger /
battery, and then repeat forever.
Prevent this reboot loop by ignoring auto-power-up when the battery is
critically low, regardless of system unlocked status.
BUG=chrome-os-partner:48339
TEST=Verify power-up is prevented on no-battery chell w/ donette. Then,
run 'powerbtn' on EC console and verify system powers on (and
overcurrents).
BRANCH=None
