IOW, in omap_device_build_from_dt(), conditionalize: pdev->dev.pm_domain = &omap_device_pm_domain; then none of the callbacks will be called in the first place, so they won't need to be conditionalized. Without a PM domain, they will fallback to the bus level hooks, which in this case will be the platform_bus hooks, which will just call the pm_generic functions.
