#     powerpc/pseries/mobility: refactor node lookup during DT update
#     
#     In pseries_devicetree_update(), with each call to ibm,update-nodes the
#     partition firmware communicates the node to be deleted or updated by
#     placing its phandle in the work buffer. Each of delete_dt_node(),
#     update_dt_node(), and add_dt_node() have duplicate lookups using the
#     phandle value and corresponding refcount management.
#     
#     Move the lookup and of_node_put() into pseries_devicetree_update(),
#     and emit a warning on any failed lookups.
