Hello, This series re-factors ufshcd_get_pwr_dev_param in vendors' drivers. This function is for vendors to decide finally agreed attributes for power mode change if vendors define their host capability in struct ufs_dev_params. Because it is using by both ufs-qcom and ufs-hisi currently and may be used in other vendors in the future, simply re-factor it and then evevry vendors can reuse it.
