Revert "drm: of: Lookup if child node has panel or bridge"
Commit '80253168dbfd ("drm: of: Lookup if child node has panel or
bridge")' attempted to simplify the case of expressing a simple panel
under a DSI controller, by assuming that the first non-graph child node
was a panel or bridge.
Unfortunately for non-trivial cases the first child node might not be a
panel or bridge. Examples of this can be a aux-bus in the case of
DisplayPort, or an opp-table represented before the panel node.
In these cases the reverted commit prevents the caller from ever finding
a reference to the panel.
This reverts commit '80253168dbfd ("drm: of: Lookup if child node has
panel or bridge")', in favor of using an explicit graph reference to the
panel in the trivial case as well.
