power: bq25890: Enable continuous conversion for ADC at charging

Browse Source 
[ Upstream commit 80211be1b9dec04cc2805d3d81e2091ecac289a1 ]

Instead of one shot run of ADC at beginning of charging, run continuous
conversion to ensure that all charging-related values are monitored
properly (input voltage, input current, themperature etc.).
