Add a device node to drm_encoder which corresponds with the port node
in the DT description of the encoder. This allows drivers to find the
of_graph link between a crtc and an encoder.

Is this the port that gets used in patch 3/22?
It looks like it.

So this would break bisectability. Can we order patches
sequentially so that git bisect keeps working.

Thanks
