REVISION SUMMARY
  This change is a prerequisite for multi-GPU support.
  
  Overall, the desired design:
  
  - there are multiple DrmDevice devices;
  - all DrmDevice devices form master-slave relationship, where master
  
  device, aka primary device, is used for all rendering and exporting
  PRIME buffers;
  
  - Each DRM object is associated with one particular DRM device.
  
  In general it would be nice to refactor rendering infrastructure in
  kwin, perhaps we need several "renderers." One that is used for rendering
  the scene, and the other one is used to render cursors (animated cursors
  is PITA).
  
  The DrmDevice class is currently a no-op. I submitted this change just
  to let you know what I'm working on.
