Subject: [PATCH] crypto: caam: fix PM operations definition

From: Arnd Bergmann <arnd@...db.de>

The newly added PM operations use the deprecated SIMPLE_DEV_PM_OPS() macro,
causing a warning in some configurations:

drivers/crypto/caam/ctrl.c:828:12: error: 'caam_ctrl_resume' defined but not used [-Werror=unused-function]
  828 | static int caam_ctrl_resume(struct device *dev)
      |            ^~~~~~~~~~~~~~~~
drivers/crypto/caam/ctrl.c:818:12: error: 'caam_ctrl_suspend' defined but not used [-Werror=unused-function]
  818 | static int caam_ctrl_suspend(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~
drivers/crypto/caam/jr.c:732:12: error: 'caam_jr_resume' defined but not used [-Werror=unused-function]
  732 | static int caam_jr_resume(struct device *dev)
      |            ^~~~~~~~~~~~~~
drivers/crypto/caam/jr.c:687:12: error: 'caam_jr_suspend' defined but not used [-Werror=unused-function]
  687 | static int caam_jr_suspend(struct device *dev)
      |            ^~~~~~~~~~~~~~~

Use the normal DEFINE_SIMPLE_DEV_PM_OPS() variant now, and use pm_ptr() to
completely eliminate the structure in configs without CONFIG_PM.
