CONFIG_PM is defined when CONFIG_PM_SLEEP or CONFIG_PM_RUNTIME is defined,
however suspend and resume methods are only valid in the context of
CONFIG_PM_SLEEP. If only CONFIG_PM_RUNTIME is defined we get the following
warning (courtesy of Geerts randconfig builds):
lm8323.c: warning: 'lm8323_resume' defined but not used

/*
* We don't need to explicitly suspend the chip, as it already switches off
* when there's no activity.
