> Track CQ polling credits across owner-bit wraps and serialize arming

> advancing an outstanding arm, and update the hardware consumer position
> when polling exhausts its credits.
>
> Expose the allocated CQ capacity to the core. Pull the explicit-index
> GDMA doorbell helper and its declaration forward here because CQ arming
> is its first consumer; ordinary GDMA doorbells retain their zero client
> offset. RC-specific PSN doorbell use is introduced later.
>
> Preserve the baseline's dynamic interrupt moderation doorbell with a
> zero client offset. Read CQ owner bits through the scattered backing
> pages when the queue allocation falls back to non-contiguous memory.
