These macros allow 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. Note that this driver should probably use the DEFINE_RUNTIME_DEV_PM_OPS() macro instead, which will provide .suspend/.resume callbacks, pointing to pm_runtime_force_suspend() and pm_runtime_force_resume() respectively; unless those callbacks really aren't needed.
