SDVO is entirely hidden by the drm_encoder interface; some of the
controls (like TV encoder parameters) are exposed through DRM
properties, others are used in the basic configuration of the device.
I'm not sure we need a new abstraction that subsumes both DSI and SDVO,
but we may need a DSI library that can be used by both DRM and other
parts of the kernel.
