regulator: s5m8767: Fix carried over ena_gpio assignment
During registration of regulators if external control for regulator was set in DTS the ena_gpio and ena_gpio_flags fields of regulator_config were set to proper values. However the same regulator_config was used in next iterations of loop so the ena_gpio fields carried over to next regulators. The issue was not observed as ena_gpio is supported only for Buck9 regulator which is often the last regulator parsed from DTS. Be sure to clear ena_gpio config fields before registering the regulator.
