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. Note that the behaviour is slightly different than before; the original code wrapped the suspend/resume with #ifdef CONFIG_PM guards, which resulted in these functions being compiled in but never used when CONFIG_PM_SLEEP was disabled. Now, those functions are only compiled in when CONFIG_PM_SLEEP is enabled.
