net/mana: add 32-bit short doorbell
Add 32-bit short doorbell support.
Ring short doorbell when running in 32-bit applications.
Both 32-bit and 64-bit doorbells are supported by mana hardware on
same platform. 32-bit applications cannot use 64-bit doorbells.
64-bit applications can use 32-bit doorbells, however the performance
would greatly suffer and it is not recommended.

net/mana: optimize completion queue by batch processing
We can poll completion queues in a batch to speed up completion processing.
Also, the completion data doesn't need to be copied out of the hardware
queue and they can be passed as pointers to be consumed by the RX/TX code.
