drm/nouveau: tidy connector/encoder creation a little
Create connectors before encoders to avoid having to do another loop across encoder list whenever we create a new connector. This allows us to pass the connector to the encoder creation functions, and avoid using a create_resources() callback since we can now call it directly. This can also potentially modify the connector ordering on nv50. On cards where the DCB connector and encoder tables are in the same order, things will be unchanged. However, there's some cards where the ordering between the tables differ, and in one case, leads us to naming the connectors "wrongly". Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
