charge_ramp: Fix OC detection on chargers which recover quickly
If VBUS is lost and then quickly recovers, we may detect the re-presence
of the charger before charge_ramp has been informed about the loss. In
this case, charge manager's supplier registration time will precede our
ACTIVE_OC_INFO timestamp. Fix our timestamp comparison to correctly
detect OC in this case.
In addition, correctly mark all OC events stale once we have encountered
a disconnect / reconnect that we determine not to be related to OC.
BUG=chrome-os-partner:56367
TEST=Manual on reef, verify Motorola 800mA DCP charger settles at ~800mA
after OC.
BRANCH=reef
