is not defined, SIMPLE_DEV_PM_OPS is equivalent to an empty function. In this case,
the defination of svs_resume and svs_suspend is meaningless.

Fix build error:
drivers/soc/mediatek/mtk-svs.c:1515:12: error: ‘svs_resume’ defined but not used [-Werror=unused-function]
drivers/soc/mediatek/mtk-svs.c:1481:12: error: ‘svs_suspend’ defined but not used [-Werror=unused-function]
