This is small fixes for extcon driver.

MAX77693 extcon driver
- Add 'static' keryword to internal data structure
- Fix return value using 'ret' instead of hardcoding

MAX8997 extcon driver
- Use dev_err() instead of pr_err()
- Fix return value using 'ret' instead of hardcoding

drivers/extcon/extcon-max77693.c

  * extcon-max77693 driver use 'default_init_data' to bring up base operation
