RDMA/hns: Recover 1bit-ECC error of RAM on chip
Since ECC memory maintains a memory system immune to single-bit errors,
add support for correcting the 1bit-ECC error, which prevents a 1bit-ECC
error become an uncorrected type error. When a 1bit-ECC error happens in
the internal ram of the ROCE engine, such as the QPC table, as a 1bit-ECC
error caused by reading, the ROCE engine only corrects those 1bit ECC
errors by writing.
