We thus need to add HAS_IOPORT as dependency for those drivers using them. There is also a direct and hard coded use in cirrus.c which according to the comment is only necessary during resume. Let's just skip this as for example s390 which doesn't have I/O port support also doesen't support suspend/resume.
