To be able to perform page flips in DRM without flicker we need to be able to notify the rcar-du module when the VSP has completed its processing. We must not have bidirectional dependencies on the two components to maintain support for loadable modules, thus we extend the API to allow a callback to be registered within the VSP DRM interface.
