RDMA/bnxt_re: Add support for CQ rx coalescing
RoCE message rate performance is heavily degraded
without the use of cq coalescing. With proper coalescing,
message rates get better. Furthermore, coalescing
significantly reduces contention on the PCIe Root
Complex/Memory subsystems.
Add the changes to configure CQ rx colascing parameters
based on adapter revision when CQ is created.
