[PATCH v2 -next] crypto: sl3516 - Fix build warning without CONFIG_PM

[YueHaibing]

drivers/crypto/gemini/sl3516-ce-core.c:345:12:
 warning: ‘sl3516_ce_pm_resume’ defined but not used [-Wunused-function]
 static int sl3516_ce_pm_resume(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~

The driver needs PM, otherwise clock and resets are never set.
So make it depends on PM to fix this warning.
