Add the ability to pass DSI HS clock frequency constraints between
neighboring DSI bridges via struct drm_bridge_state . This way the
DSI HS clock frequency negotiation can be implemented instead of
the current ad-hoc method where each bridge attempts to guess the
neighbor HS clock frequency setting or expectation.
