net: mana: Define data structures for protection domain and memory registration
...
The MANA hardware support protection domain and memory registration for use
in RDMA environment. Add those definitions and expose them for use by the
RDMA driver.

net: mana: Define and process GDMA response code GDMA_STATUS_MORE_ENTRIES
...
When doing memory registration, the PF may respond with
GDMA_STATUS_MORE_ENTRIES to indicate a follow request is needed. This is
not an error and should be processed as expected.

net: mana: Define max values for SGL entries
...
The number of maximum SGl entries should be computed from the maximum
WQE size for the intended queue type and the corresponding OOB data
size. This guarantees the hardware queue can successfully queue requests
up to the queue depth exposed to the upper layer.
