regulator: max77693: Fix use of uninitialized regulator config
Driver allocated on stack struct regulator_config but didn't initialize it fully. Few fields (driver_data, ena_gpio) were left untouched. This lead to using random ena_gpio values as GPIOs for max77693 regulators. On occasion these values could match real GPIO numbers leading to interfering with other drivers and to unsuccessful enable/disable of regulator.
