The Versal2 CPM6 host controller is DesignWare-based and supports PCIe Gen6 operation at up to 64 GT/s per lane. It is currently handled by the same driver and match data (NULL) as the existing MDB host controller, but CPM6 uses a newer IP revision and differs in legacy INTx register offsets. Use a separate compatible to allow CPM6-specific handling once legacy interrupt support is validated.
