hwmon: (ina3221) Add INA3221_CONFIG to volatile_table
The MSB (15th bit) of INA3221_CONFIG is a self-clear reset bit. So this register should be added to the volatile_table of the regmap_config. Otherwise, we will see this bit is sticky in the regcache which might accidentally reset the chip when an actual write happens to the register. This might not be a severe bug for the current code line since there's no second place touching the INA3221_CONFIG except the reset routine in the probe().
