scsi: ufs: ufs-mediatek: Fix build error and type mismatch
If CONFIG_PM_SLEEP is not set.
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-, will fail:

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.
