The fwnode graph API has fwnode_graph_get_endpoint_by_id() which can also
be used to obtain endpoints within a port. It does the same than
of_graph_get_endpoint_by_regs() with the addition that it also has a
flags field to allow e.g. returning endpoints with regs higher than
requested (FWNODE_GRAPH_ENDPOINT_NEXT).

Most users dealing with endpoints on fwnode property API use this, could
something like this be done on OF as well? Probably a similar flag would be
needed though.
