Philip Chen bf62593ebd charge_state_v2: Throttle AP in high battery discharge current 
When EC sees discharge current hit BAT_MAX_DISCHG_CURRENT,
we kick off a timer and ask AP to throttle.

Then EC keeps monitoring discharge current. If the current doesn't
drop below BAT_MAX_DISCHG_CURRENT - BAT_OCP_HYSTERESIS, we restart
the timer and notify AP again, which shouldn't happen unless
AP misses or ignores the first notification.

When the timer expires, which means EC hasn't seen over-current
for BAT_OCP_TIMEOUT_US, we ask AP to stop throttling.

BUG=b:74321682, chromium:838754
BRANCH=scarlet
TEST=manually test on scarlet, confirm EC sends
EC_HOST_EVENT_THROTTLE_START and EC_HOST_EVENT_THROTTLE_STOP
host events when entering/exiting OCP.
