Now with ttm_buffer_object being a subclass of drm_gem_object we can easily lookup ttm_buffer_object for a given drm_gem_object, which in turn allows to create common helper functions. This patch starts off with a drm_gem_ttm_print_info() helper function which adds some ttm specific lines to the debug output.
