Currently, yenta_dev_suspend_noirq(), yenta_dev_resume_noirq(), and
yenta_pm_ops are covered by "#ifdef CONFIG_PM", which results in
compiler warnings in kernels built with CONFIG_PM_SLEEP=n and
CONFIG_PM=y:

  drivers/pcmcia/yenta_socket.c:1322:12: warning: ‘yenta_dev_resume_noirq’ defined but not used [-Wunused-function]
   1322 | static int yenta_dev_resume_noirq(struct device *dev)
        |            ^~~~~~~~~~~~~~~~~~~~~~
  drivers/pcmcia/yenta_socket.c:1303:12: warning: ‘yenta_dev_suspend_noirq’ defined but not used [-Wunused-function]
   1303 | static int yenta_dev_suspend_noirq(struct device *dev)
        |            ^~~~~~~~~~~~~~~~~~~~~~~

This affects kernels built without suspend and hibernation.

Avoid these warnings by using "#ifdef CONFIG_PM_SLEEP".

Fixes: 3daaf2c7aae8 ("pcmcia: Make use of the helper macro SET_NOIRQ_SYSTEM_SLEEP_PM_OPS()")
