As pointed out by the documentation for drm_dp_aux_register(), drm_dp_aux_init() should be used in situations where the AUX channel for a display driver can potentially be registered before it's respective DRM driver. This is the case with Tegra, since the DP aux channel exists as a platform device instead of being a grandchild of the DRM device.
Since we're about to add a backpointer to a DP AUX channel's respective DRM device, let's fix this so that we don't potentially allow userspace to use the AUX channel before we've associated it with it's DRM connector.
