power: supply: bq24190_charger: Limit over/under voltage fault logging
If the charger is unplugged before the battery is full we may
see an over/under voltage fault. Ignore this rather then emitting
a message or uevent.
This fixes messages like these getting logged on charger unplug + replug:
bq24190-charger 15-006b: Fault: boost 0, charge 1, battery 0, ntc 0
bq24190-charger 15-006b: Fault: boost 0, charge 0, battery 0, ntc 0
