From: Suzuki K Poulose <suzuki.poul...@arm.com>
If a graph node is not found for a given node, of_get_next_endpoint()
will emit the following error message :
OF: graph: no port node found in /<node_name>
If the given component doesn't have any explicit connections (e.g,
ETE) we could simply ignore the graph parsing.
