This isn't compliant with the TDA998x binding, and is very likely to
screw Jean's work on adding audio support.  See emails on lakml and
Documentation/devicetree/bindings/drm/i2c/tda998x.txt (which looks
like it needs updating to include the ports stuff.)

Also, the whole question of representing connectors in a DRM model is
yet to be established.  Yes, DT should describe the hardware, but we
don't yet know _how_ to describe physical connectors with stuff
implemented on top of DRM yet, and we have nothing that makes use of
this.

Also note that ePAPR requires a reg= property if you specify a
unit-address (the bit after the @ sign) so the above is non-compliant
with ePAPR as well.
