drm/msm/dsi: Support NO_CONNECTOR bridges
For now, since we have a mix of bridges which support this flag, which
which do *not* support this flag, or work both ways, try it once with
NO_CONNECTOR and then fall back to the old way if that doesn't work.
Eventually we can drop the fallback path.
v2: Add missing drm_connector_attach_encoder() so display actually comes
up when the bridge properly handles the NO_CONNECTOR flag
