Yangyang Li c9813b0b99 RDMA/hns: Support SRQ record doorbell 
Compared with normal doorbell, using record doorbell can shorten the
process of ringing the doorbell and reduce the latency.

Add a flag HNS_ROCE_CAP_FLAG_SRQ_RECORD_DB to allow FW to
enable/disable SRQ record doorbell.

If the flag above is set, allocate the dma buffer for SRQ record
doorbell and write the buffer address into SRQC during SRQ creation.

For userspace SRQ, add a flag HNS_ROCE_RSP_SRQ_CAP_RECORD_DB to notify
userspace whether the SRQ record doorbell is enabled.
