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 ALTERA_TSE depend on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset:
------ ERROR: modpost: "devm_ioremap" [drivers/net/ethernet/altera/altera_tse.ko] undefined! ------
