IB/mlx4: Add diagnostic hardware counters
Expose IB diagnostic hardware counters.
The counters count IB events and are applicable for IB and RoCE.
The counters can be divided into two groups, per device and per port.
Device counters are always exposed.
Port counters are exposed only if the firmware supports per port counters.
rq_num_dup and sq_num_to are only exposed if we have firmware support
for them, if we do, we expose them per device and per port.
rq_num_udsdprd and num_cqovf are device only counters.
rq - denotes responder.
sq - denotes requester.
