While bridge/panel detection was initially relying on the usual port/ports-based of graph detection, it was recently changed to perform the lookup on any child node that is not port/ports instead when such a node is available, with no fallback on the usual way.
This results in breaking detection when a child node is present but does not contain any panel or bridge node, even when the usual port/ports-based of graph is there.
In order to support both situations properly, this commit reworks the logic to try both options and not just one of the two: it will only return -EPROBE_DEFER when both have failed.
