Subject: RDMA/hns: Update the PD&CQE&MTT specification in hip08
Patch-mainline: v4.15-rc1
Git-commit: 3180236cceeb3d66e45f6395501f3d315beae4c1
References: bsc#1104427 FATE#326416
This patch updates the PD specification to 16M for hip08. And it
updates the numbers of mtt and cqe segments for the buddy.
As the CQE supports hop num 1 addressing, the CQE specification is
64k. This patch updates to set the CQE specification to 64k.
