Add support for thread domain (TD) and parent domain (PAD). Extend the orginal hns_roce_pd struct to hns_roce_pad by adding the new hns_roce_td struct. When a parent domain holds a thread domain, the associated data path will be set to lock-free mode to improve performance. Signed-off-by: Junxian Huang <huangjunxian6@hisilicon.com>
