In a configuration with CONFIG_SCSI_UFS_MEDIATEK set to 'm' and
CONFIG_PM set to 'n', errors occur at compile time:
====
../drivers/ufs/host/ufs-mediatek.c: In function ‘ufs_mtk_runtime_suspend’:
../drivers/ufs/host/ufs-mediatek.c:1621:8: error: implicit declaration of function ‘ufshcd_runtime_suspend’; did you mean ‘ufs_mtk_runtime_suspend’? [-Werror=implicit-function-declaration]
../drivers/ufs/host/ufs-mediatek.c: In function ‘ufs_mtk_runtime_resume’:
../drivers/ufs/host/ufs-mediatek.c:1636:9: error: implicit declaration of function ‘ufshcd_runtime_resume’; did you mean ‘ufs_mtk_runtime_resume’? [-Werror=implicit-function-declaration]
====
Fix these errors by guarding the runtime PM functions with CONFIG_PM.
