regulator: core: Request GPIO before creating sysfs entries
regulator_attr_is_visible (which is a .is_visible callback of regulator_dev_group attribute_grpup) checks rdev->ena_pin to decide if "status" file should be present in sysfs. This field is set at the end of regulator_ena_gpio_request so it has to be called before device_register() otherwise this test will always fail, causing "status" file to not be visible. Since regulator_attr_is_visible also tests for is_enabled() op, this problem is only visible for regulators that does not define this callback, like regulator-fixed.c.
