power: supply: bq24190_charger: Always call power_supply_get_battery_info()

power_supply_get_battery_info() now also supports getting battery_info
on boards not using dt/of. Remove the of_node check. If neither of nor
other battery-info is present the function will fail making this change
a no-op in that case.
