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

fwnode_graph_get_endpoint_count() was added in 2021 by
commit c87b8fc56966 ("device property: Implement
fwnode_graph_get_endpoint_count()")

but has never been used.

fwnode_graph_get_remote_port() has been unused since 2017's
commit 6a71d8d77795 ("device property: Add fwnode_graph_get_port_parent")

Remove them.

Hi David,

Thanks for the patch.

Both of the functions also exist to span the same scope as the OF API,
hence they should exist as long as the OF framework continues to provide
these API functions. The equivalent OF functions are used by drivers
currently.
