Subject: RDMA/hns: Update some fields of qp context
Patch-mainline: v4.20-rc1
Git-commit: 2362cceef3f4cbd382f338327097f98795f6b91e
References: bsc#1104427 FATE#326416
The hip08 hardware has two version. the version id are 0x20 and 0x21
according to the pci revision. It needs to adjust some fields for
extending new features. The specific updates include:
1. Add some fields for supporting new features by enabling some reserved
fields in 0x20 version.
2. remove some fields which the user is not visiable in order to support
the extend features.
3. Init some fields with zero.
These updates is compatible with 0x20 version.
