[PATCH] extcon: checkpatch warning removal

[anish kumar <anish198519851985@gmail.com>]

From: anish kumar <anish198519851985@gmail.com>

without this patch we get below warning:
WARNING: externs should be avoided in .c files
132: FILE: extcon/extcon-class.c:
int extcon_set_state(struct extcon_dev *edev, u32 state);

So just removed the declaration.
