[2.6 patch] i386 APIC Kconfig cleanups

[Adrian Bunk <bunk@stusta.de>]

The patch below contains the following changes to arch/i386/Kconfig:
- update the X86_UP_APIC and X86_UP_IOAPIC help texts:
  - in the SMP case, these options are not visible
  - today, it's no longer only "a small number of uniprocessor systems"
    that have an IO-APIC
- there were two X86_LOCAL_APIC and two X86_IO_APIC options -
  in both cases, merge them
- move X86_VISWS_APIC to the other APIC options

Please review this patch (it shouldn't have any visible effects).
