From: Lyude Paul <lyude@redhat.com>
[ Upstream commit 9962849d0871f5e53d0e3b3d84561f8f2847fbf4 ]
Since encoder mappings for connectors are exposed to userspace, we should be attaching the encoder before exposing the connector to userspace. Just a drive-by fix for an issue I noticed while fixing up usages of drm_dp_aux_init()/drm_dp_aux_register() across the tree.
