These clock supply the coresight tracing modules, PTM, TPIU, ETB and replicator. Without these clock, the coresight tracing can not be operated. While this does change the ABI, it does so by extending the existing clock-output-names, therefore if an old software is used with new DT, the coresight tracing parts will likely fail to probe, otherwise if new software is used with an old DT, there is no impact.
