pcmcia: do not use ioports < 0x100 on x86

On x86 systems using ACPI _CRS information -- now the default for
post-2008 systems -- the PCI root bus no longer pretends to be
offering the root ioport_resource. To avoid accidentally hitting
some platform / system device, use only I/O ports >= 0x100 for
PCMCIA devices on x86.
