power: Rerun AICL if charging disable/enable

Browse source 
It is found that the USB settled ICL drop down when battery
charging is disabled for full charge, but the ICL does not
adaptively increase for incremental system load or recharge.
In that case, it draws current from battery even a charger
is attached.
In order to recover from that situation, rerun AICL is an
effective way to recover the USB ICL.
