rk817-charger
~~~~~~~~~~

Required properties :
 - compatible: "rk817,charger"
 - min_input_voltage: minimum voltage from adapter
 - max_input_current: maximum current from adapter
 - max_chrg_current: maximum current for battery charge
 - max_chrg_voltage: maximum charge voltage for battery
 - chrg_finish_cur: charging termination current

Optional properties :
 - virtual_power: test mode for none battery
 - power_dc2otg: dc can provide supply for otg 5v
 - dc_det_adc: dc detect by saradc
