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 driver should probably use the DEFINE_RUNTIME_DEV_PM_OPS() macro, as the system suspend/resume callbacks seem to not do anything more than triggering the runtime-PM states.
