During deletion of device nodes of_find_device_by_node() is called in
order to set the device_node pointer of the device corresponding to
the to-be-deleted node to NULL. This is not necessary anymore as the
live tree should not be deleted.
This fixes problems with deep-probe support. of_find_device_by_node()
calls of_device_ensure_probed(), but this may only be called on the
live tree, not on arbitrary nodes that shall be deleted.
