v4l: vsp1: extend VSP1 module API to allow DRM callbacks

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.

v2:
 - vsp1_du_setup_lif() uses config structure to set callbacks
 - vsp1_du_pipeline_frame_end() moved to interrupt section
 - vsp1_du_pipeline_frame_end registered in vsp1_drm_init()
   meaning of any NULL values
 - removed unnecessary 'private data' variables
