scsi: ufs: ufs-mediatek: Support clk-scaling to optimize power consumption Provide clk-scaling feature in MediaTek UFS platforms. MediaTek platform supports clk-scaling by switching parent clock mux of UFSHCI main clocks: ufs_sel. The driver needs to prevent changing the rate of ufs_sel because its parent PLL clock may be shared between multiple IPs. In order to achieve this goal, the maximum and minimum clock rates of ufs_sel defined in dts should match the rate of "ufs_sel_max_src" and "ufs_sel_min_src" respectively.
