Orphan nodes have been introduced recently.

mark_local_phandles() and mark_local_exports() mark phandles and export
symbols as local when they reference a local node (i.e. a node in the
current device-tree).

update_phandles_ref() and update_exports_ref() update references
pointing to local nodes.

Those phandles, export symbols and references can involve orphan trees.

Indeed, even if an orphan node itself is not present in the current
device-tree, its subnodes are fully described in the current device-tree
and so, those subnodes have to be considered as local nodes.

Update those functions to handle orphan nodes.
