charge_manager: Enter safe mode at boot
Charge port / current selection often needs to be significantly altered
when a battery cannot provide sufficient charge, so have charge_manager
initially enter safe mode. After a battery with sufficient capacity has
been identified, charge manager will leave safe mode, and port / current
selection will return to standard rules.
BUG=chromium:777596
BRANCH=None
TEST=Pass charge_manager unit tests. On kevin, remove battery, attach
Apple PD charger, verify safe mode is not exited and device does not
brown out. Hot-plug battery and verify safe mode is exited. Next,
remove battery, attach to Samus, verify safe mode is not exited and
device doesn't brown out. Hot-plug battery, verify that safe mode is
exited and no active charge port, due to dual-role exclusion.
