pchg: Notify host of full charge
Currently, full charge status is implied by capacity = 100 and
PCHG_STATE_DETECTED (i.e. state='not charging'). If the charger
stops charging before 100% (for battery health control), this
condition doesn't work.
This patch makes PCHG send PCHG_STATE_FULL explicitly when it sees
the soc goes above the threshold in PCHG_STATE_DETECTED.
BUG=b:179390065,b:173235954
BRANCH=trogdor
TEST=CoachZ. Charge till 96% and verify PCHG0/state becomes 'Full'.
