commit f54912b228a8df6c0133e31bc75628677bb8c6e5 upstream.
If CONFIG_PM_SLEEP is not set.
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-, will fail:
drivers/ufs/host/ufs-mediatek.c: In function ‘ufs_mtk_vreg_fix_vcc’:

cc1: some warnings being treated as errors
The declaration of func "ufshcd_system_suspend()" depends on
CONFIG_PM_SLEEP, so the function wrapper ufs_mtk_system_suspend() should
wrapped by CONFIG_PM_SLEEP too.
