charge: resolve sc85xx charge icon dont disappear

Browse source 
There are 2 cases
1.SC85XX reverse voltage from battery to VBUS through sc8551
mosfet parasitic diode. this case vbus voltage is less than battery
voltage

2. SC85XX reverse voltae from battery to VBUS through sc8551 working
mosfet. this case vbus is about 2:1 battery voltage
