From: "Dr. David Alan Gilbert" <linux@treblig.org>

extcon_get_edev_name() has been unused since it was added in 2015 by
commit 707d7550875a ("extcon: Add extcon_get_edev_name() API to get the
extcon device name")

extcon_get_property_capability() has been unused since it was added
in 2016 by
commit ceaa98f442cf ("extcon: Add the support for the capability of each
property")
(It seems everyone just uses extcon_get_property)

extcon_set_property_sync() has been unused since it was added in 2016
by
commit a580982f0836 ("extcon: Add the synchronization extcon APIs to
support the notification")
Everyone seems to use the none _sync version, and there's one place
where they just call sync after it.

Remove them.
