Having a default optee node in a soc devicetree is not really good.
For one there is no guarantee that any tee got loaded and there's even
the possibility that a completely different TEE got loaded.
OP-Tee however will insert relevant nodes to the devicetree (firmware
+reserved memory sections) during its own startup, so there really is
no need to provide a default node.
