platform/x86: amd-pmc: Fix build error unused-function 

If CONFIG_SUSPEND and CONFIG_DEBUG_FS are not set.

compile error:
drivers/platform/x86/amd-pmc.c:323:12: error: ‘get_metrics_table’ defined but not used [-Werror=unused-function]
 static int get_metrics_table(struct amd_pmc_dev *pdev, struct smu_metrics *table)
            ^~~~~~~~~~~~~~~~~
drivers/platform/x86/amd-pmc.c:298:12: error: ‘amd_pmc_idlemask_read’ defined but not used [-Werror=unused-function]
 static int amd_pmc_idlemask_read(struct amd_pmc_dev *pdev, struct device *dev,
            ^~~~~~~~~~~~~~~~~~~~~
drivers/platform/x86/amd-pmc.c:196:12: error: ‘amd_pmc_get_smu_version’ defined but not used [-Werror=unused-function]
 static int amd_pmc_get_smu_version(struct amd_pmc_dev *dev)
            ^~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

To fix building warning, wrap all related code with CONFIG_SUSPEND or CONFIG_DEBUG_FS.
