NC-SI hardware arbitration output.
If the baseboard supports multiple DPUs cards connected to the same RBT
interface, it should implement logic that connects the RBT_ARB_OUT pin of
the first populated DPU card to its RBT_ARB_IN pin if it is the only card
present or to the RBT_ARB_IN pin of the next populated card and so on
sequentially for all cards on the specified RBT bus to ensure the arbitration
ring is complete. This logic should bypass slots that are not populated or
powered off.
