[PATCH 14/18] drm/ttm: Remove struct ttm_bo_global_ref and helpers

[Thomas Zimmermann]

The struct ttm_bo_global_ref data type providede a workaround for passing
an instance of struct ttm_mem_global to ttm_bo_global_init().

This functionality has been replaced by struct ttm_global and all drivers
have been converted. struct ttm_bo_global_ref is obsolete.
