On the surface, I see why you'd ask, but we want separate kit and
baseboard, because once the DSI video interface is working, we'll have
different variants for HDMI video and LVDS video using DSI bridge
chips. Since they will be mutually exclusive, they'll go at the kit
level and share the common baseboard items between them.
