Subject: [PATCH v8 02/10] scsi: ufs: ufs-qcom: No need to set hs_rate after ufshcd_init_host_param()

In ufs_qcom_pwr_change_notify(), host_params.hs_rate has been set to
PA_HS_MODE_B by ufshcd_init_host_param(), hence remove the duplicated line
of work. Meanwhile, removed the macro UFS_QCOM_LIMIT_HS_RATE as it is only
used here.
