The local variable np in function of_unittest_platform_populate takes
the return value of of_find_node_by_path, which gets a node but does not
put it. If np is not put before return it may cause a memory leak. Hence
put np before a return statement.
Issue found with Coccinelle.

- The clock-lanes property is not needed for the sensors do not support
  lane reordering. (The information possibly present in existing clock-lane
  properties is simply not used.)

- There's no need to refer to the sensor device in the DT example, thus
  remove the label.

- Rename the "camera" device node as "camera-sensor".

- Rename the endpoint label as "smiapp_ep" (was: "smiapp_1_1"). There is
  in practice only one anyway.

- Remove the remote-endpoint documentation (it is covered by
  graph.txt to which video-interfaces.txt refers to).

- Add a note on the port and endpoint nodes.

These changes make the smiapp bindings a better example.
