[PATCH v2 2/4] drm/bridge: ti-sn65dsi86: Make connector creation optional

[Kieran Bingham]

From: Laurent Pinchart <laurent.pinchart+rene...@ideasonboard.com>

Now that the driver supports the connector-related bridge operations,
make the connector creation optional. This enables usage of the
sn65dsi86 with the DRM bridge connector helper.
