drm: Add reservation_object to drm_gem_object
Many users of drm_gem_object embed a struct reservation_object into
their subclassed struct, so let's add one to struct drm_gem_object.
This will allow removing the reservation object from the subclasses
and removing the ->gem_prime_res_obj callback.
With the addition, add a drm_gem_reservation_object_wait() helper
function for drivers to use in wait ioctls.
