Add support for the 1bit ECC error recovery by abnormal interrupt reporting
and adjusts the structure of the abnormal interrupt handler.

The following is the outline of each patch:
(1)#1~#4: Cleanup and bugfix for the abnormal interrupt handler.
(2)#5: Support for the 1bit ECC error recovery.

Changes since v1:
* Embed ecc_work into structure hns_roce_dev, no longer dynamically allocated in #5.
* Add the const keyword to the string array that does not change in #5.
* v1 Link: https://patchwork.kernel.org/project/linux-rdma/cover/20220624110845.48184-1-liangwenpeng@huawei.com/

Haoyue Xu (5):
  RDMA/hns: Remove unused abnormal interrupt of type RAS
  RDMA/hns: Fix the wrong type of return value of the interrupt handler
  RDMA/hns: Fix incorrect clearing of interrupt status register
  RDMA/hns: Refactor the abnormal interrupt handler function
  RDMA/hns: Recover 1bit-ECC error of RAM on chip
