    drm: Stop using an embedded struct drm_device in driver softcs
    
    * All drm drivers use a struct drm_device record but are free to
      allocate it by themselves in different ways or let the generic
      drm subsystem code do it.
    
    * This drm_device record can even be part of another data structure,
      dynamically or statically allocated.
    
    * We cannot just assume the length of a drm_device structure in the
      softc memory block will be enough to store all driver private data.
    
    * Make the drm softc the equivalent of a void* pointer and let the
      upstream code behave as expected on Linux
