ab8500-bm: Quick re-attach charging behaviour

Browse source 
Due to a bug in some AB8500 ASICs charger removal cannot always
be detected if the removal and reinsertion is done to close in time.
This patch detects above described case and handles the situation
so that charging will be kept turned on.
