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 depend PCMCIA on HAS_IOMEM so that it won't be built to
cause below compiling error if PCI is unset.
------
ld: drivers/pcmcia/cistpl.o: in function `set_cis_map':
cistpl.c:(.text+0x1202): undefined reference to `ioremap'
ld: cistpl.c:(.text+0x13b0): undefined reference to `iounmap'
ld: cistpl.c:(.text+0x14a6): undefined reference to `iounmap'
ld: cistpl.c:(.text+0x1544): undefined reference to `ioremap'
ld: drivers/pcmcia/cistpl.o: in function `release_cis_mem':
cistpl.c:(.text+0x3f14): undefined reference to `iounmap'
------
Besides, many other Kconfig option, e.g IPWIRELESS, PCMCIA_PCNET,
PCMCIA_FMVJ18X, PCMCIA_SMC91C92 which depends on PCMCIA also will
cause compiling error if enabled.
