Subject: RDMA/hns: Configure mac&gid and user access region for hip08 RoCE
 driver
Patch-mainline: v4.15-rc1
Git-commit: 7afddafa8403842a2dd50cd6c696a80b1f74a22f
References: bsc#1104427 FATE#326416

In hip08, the user access region(UAR) pfn is calculated
from pci device memory resource.

This patch mainly sets mac and gid table by configuring
the relevant registers and updates the uar pfn for hip08 SoC.
