This patch removes the deprecated notifier API of extcon framework and then use
the new extcon API[2] with the unique id[1] to indicate the each external
connector. Alter deprecated API as following:
- extcon_register_interest() -> extcon_register_notifier()
- extcon_unregister_interest() -> extcon_unregister_notifier()
- extcon_get_cable_state() -> extcon_get_cable_state_()

And, extcon alters the name of USB charger connector in patch[3] as following:
- EXTCON_CHG_USB_SDP /* Standard Downstream Port */
- EXTCON_CHG_USB_DCP /* Dedicated Charging Port */
- EXTCON_CHG_USB_CDP /* Charging Downstream Port */
- EXTCON_CHG_USB_ACA /* Accessory Charger Adapter */
