This macro allows the suspend and resume functions to be automatically dropped by the compiler when CONFIG_PM is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch. It also allows to drop the __maybe_unused tags.
