Can Guo 9d8528a833 scsi: ufs: ufs-qcom: Limit HS-G5 Rate-A to hosts with HW version 5
Qcom UFS hosts, with HW ver 5, can only support up to HS-G5 Rate-A due to
HW limitations. If the HS-G5 PHY gear is used, update host_params->hs_rate
to Rate-A, so that the subsequent power mode changes shall stick to Rate-A.
