We thus need to add HAS_IOPORT as dependency for those drivers using them. In the bochs driver there is optional MMIO support detected at runtime, warn if this isn't taken when HAS_IOPORT is not defined. 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.
