Providing separate initializer and release functions for struct ttm_bo_global gives drivers the option of implementing their own init and release callbacks for drm_global_references of type DRM_GLOBAL_TTM_BO. The original functions for initializing and releasing via struct ttm_bo_global_ref are wrappers around the new interfaces.
