drm/i915: Make encoder->mode_set callbacks optional
For a bunch of reasons we want to move away from the ->mode_set callbacks: All hw state setup needs to move into ->enable hooks (so that DOMS can do runtime pm) and all the configuration setup needs to move into the compute_config functions. To start with this make the enocer->mode_set callback optional. Reviewed-by: Imre Deak <imre.deak@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
