net/mlx5: Hairpin pair core object setup
Low level code to setup hairpin pair core object, deals with:
- create hairpin RQs/SQs
- destroy hairpin RQs/SQs
- modifying hairpin RQs/SQs - pairing (rst2rdy) and unpairing (rdy2rst)
Unlike conventional RQs/SQs, the memory used for the packet and descriptor
buffers is allocated by the firmware and not the driver. The driver sets
the overall data size (log).
