These drivers are typically drivers for some SoC peripheral and the device will simply physically not exist on a platform that does not provide HAS_IOMEM. This is not really any different from making the driver selectable via COMPILE_TEST for any other platform. To hit the issue you'd have to instantiate a device driver instance for a device that physically does not exist. This will always result in a failure.
