After commit 4a032827daa8 ("of: property: Simplify of_link_to_phandle()"), remote-endpoint properties created a fwnode link from the consumer device to the supplier endpoint. This is a tiny bit inefficient (not buggy) when trying to create device links or detecting cycles. So, improve this the same way we improved finding the consumer of a remote-endpoint property.
