On s390 systems (aka mainframes), it has classic channel devices for networking and permanent storage that are currently even more common than PCI devices. Hence it could have a fully functional s390 kernel with CONFIG_PCI=n, then the relevant iomem mapping functions [including ioremap(), devm_ioremap(), etc.] are not available.
Here let AL_FIC depend on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset:
------ ld: drivers/irqchip/irq-al-fic.o: in function `al_fic_init_dt': irq-al-fic.c:(.init.text+0x76): undefined reference to `of_iomap' ld: irq-al-fic.c:(.init.text+0x4ce): undefined reference to `iounmap' ------
