extcon: Remove the deprecated extcon functions
This patch removes the deprecated extcon functions using string type to identify the type of external connector. The Commit 2a9de9c0f08d61 ("extcon: Use the unique id for external connector instead of string) uses the unique id to separate the type of external connector instead of string name. - extcon_register_interest() - extcon_unregister_interest() - extcon_set_cable_state() - extcon_get_cable_state() And, extcon_register_interest() finds the first extcon device to include the requested external connector from extcon client device and then register the notifier if extcon device argument is NULL. Instead, extcon_register_notifier() supports this feature. But, this patch remains the deprecatd function definition to prevent the build break. Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
