Subject: [PATCH] rtc: stm32: Use NOIRQ_SYSTEM_SLEEP_PM_OPS()

If CONFIG_PM_SLEEP=n (e.g. m68k/allmodconfig):

    drivers/rtc/rtc-stm32.c:904:12: error: ‘stm32_rtc_resume’ defined but not used [-Werror=unused-function]
      904 | static int stm32_rtc_resume(struct device *dev)
	  |            ^~~~~~~~~~~~~~~~
    drivers/rtc/rtc-stm32.c:894:12: error: ‘stm32_rtc_suspend’ defined but not used [-Werror=unused-function]
      894 | static int stm32_rtc_suspend(struct device *dev)
	  |            ^~~~~~~~~~~~~~~~~

Indeed, the previous change mixed up the semantics between
SET_NOIRQ_SYSTEM_SLEEP_PM_OPS() and NOIRQ_SYSTEM_SLEEP_PM_OPS().
Fix this by using the modern NOIRQ_SYSTEM_SLEEP_PM_OPS() instead.
