[YueHaibing <yuehaibing@huawei.com>]

drivers/scsi/ufs/ufshcd.c:9770:12: warning: ‘ufshcd_rpmb_resume’ defined but not used [-Wunused-function]
 static int ufshcd_rpmb_resume(struct device *dev)
            ^~~~~~~~~~~~~~~~~~
drivers/scsi/ufs/ufshcd.c:9037:12: warning: ‘ufshcd_wl_runtime_resume’ defined but not used [-Wunused-function]
 static int ufshcd_wl_runtime_resume(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~~~~~
drivers/scsi/ufs/ufshcd.c:9017:12: warning: ‘ufshcd_wl_runtime_suspend’ defined but not used [-Wunused-function]
 static int ufshcd_wl_runtime_suspend(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~~~~~~

Move it into #ifdef block to fix this.
