drm/dp_mst: Factor out a helper to check the atomic state of a topology manager
Factor out a helper to check the atomic state for one MST topology manager, returning the MST port where the BW limit check has failed. This will be used in a follow-up patch by the i915 driver to improve the BW sharing between MST streams.
