charge_state_v2: Throttle AP in low battery voltage
When EC sees voltage drops below BAT_LOW_VOLTAGE_THRESH,
we kick off a timer and ask AP to throttle.
When the timer expires which means EC hasn't seen under-voltage
for BAT_UVP_TIMEOUT_US, we ask AP to stop throttling.
We reset the throttling status and do nothing when AP is off (S5).
BUG=b:73050145, 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 UVP.
