When CONFIG_PM is disabled, the prototypes for these two functions
are not visible:
drivers/mfd/intel-lpss.c:482:5: error: no previous prototype for 'intel_lpss_suspend' [-Werror=missing-prototypes]
482 | int intel_lpss_suspend(struct device *dev)
| ^~~~~~~~~~~~~~~~~~
drivers/mfd/intel-lpss.c:503:5: error: no previous prototype for 'intel_lpss_resume' [-Werror=missing-prototypes]
503 | int intel_lpss_resume(struct device *dev)
Add the same #ifdef around the definition of the unused functions,
which avoids the warning and slightly reduces the code size.
