Rename ufshcd_auto_hibern8_enable() into ufshcd_configure_auto_hibern8() since this function can enable or disable auto-hibernation. Since ufshcd_auto_hibern8_enable() is only used inside the UFSHCI driver core, declare it static. Additionally, move the definition of this function to just before its first caller.
