drm: Introduce drm_mode_object_{get,put}()
For consistency with other reference counting APIs in the kernel, add drm_mode_object_get() and drm_mode_object_put() to reference count DRM mode objects. Compatibility aliases are added to keep existing code working. To help speed up the transition, all the instances of the old functions in the DRM core are already replaced in this commit. A semantic patch is provided that can be used to convert all drivers to the new helpers.
