Use the new PM macros for the suspend and resume functions to be
automatically dropped by the compiler when CONFIG_PM_SLEEP are disabled,
without having to use #ifdef guards. If CONFIG_PM_SLEEP unused,
they will simply be discarded by the compiler.

v2: add __maybe_unused to suspend/resume functions in case CONFIG_PM is
disabled.
