Subject: [RFC PATCH 53/77] dtc: Rename add_orphan_node() to plugin_add_orphan_node()

add_orphan_node() is used when a orphan node is parsed in a plugin
(overlay) device-tree.

This function creates some device-tree nodes (/fragment@..._overlay__)
in order to merge the parsed orphan node.

This is specific to plugin device-trees and cannot be used for addon
device-trees.

In order to clarify that add_orphan_node() is specific to plugin
device-trees and to prepare the support for orphan node parsing
in the addon context, rename current add_orphan_node() to
plugin_add_orphan_node().
