FG: power_supply_property get rt9426a battery info from local value

Browse source 
1.when plug the USB cable, charger policy will trigle to get POWER_SUPPORY_PROPERTY
For rt9426a fg getting power_supply_property vaule by read i2c data, that will
make i2c busy and affect the PD sink.

2.remove useless debug info
