Only start up nonstatic sockets if both IO and MEM resources are available.

Don't auto-configure yenta sockets for PCMCIA devices if it is connected to
the root PCI bus on the x86 or x86_64 architectures. Previously, this was
handled by the "ioport_resource"/"iomem_resource" check a few lines below,
but with the new ACPI-based resource handling this doesn't catch all cases
any longer.
pci-yenta-cardbus-fix.patch and this patch should solve the initialization
time trouble. However, the ACPI-based PCI resource handling is badly
broken, IMHO:
- many resources of devices don't show up in the resource trees (
/proc/iomem and /proc/ioports) any longer. This means that PCMCIA, but
also possibly other subsystems (ISA, PnP, ...) do not know which resources
it cannot use.
- verify_root_windows() should fail if there are no iomem _or_ ioport
resources, not only if there are no iomem _and_ ioport resources.

- properly bail out in set_cis_map if call to socket driver's set_mem_map
failed
- don't abort do_mem_probe cycle if one entry failed (!CONFIG_PCMCIA_PROBE)
- don't do iomem probing in chunks larger than 0x800000 (1 << 23) as
yenta_socket and vrc4173_cardu.c fail to set_mem_map for windows equal to
or larger than (1 << 24).

This patch contains the following cleanups:
- make needlessly global code static
- remove the following unneeded EXPORT_SYMBOL's:
- ds.c: pcmcia_report_error
- ds.c: pcmcia_bus_type

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
