TP-Link routers have flash space partitioned according to the partitions
table. It may look like fixed partitioning but those partitions can be
actually reorganized. New can be added (or some removed), offsets and
sizes may change.
Fix DT to use binding for the TP-Link SafeLoader partitioning method.
