power: supply: bq24190_charger: Disallow ccc_ireg and cvc_vreg to be higher then the fwnode values

If the fwnode data as parsed by power_supply_get_battery_info() provides
max values for ccc_ireg and cvc_vreg then do not allow the user to later
set these to higher values then those specified by the firmware,
otherwise the battery might get damaged.
