move the include/asm-x86/mach-visws/ VISWS specific hardware
details include files into include/asm-x86/visws, to be used from
generic code.
No code changed.

update asm-x86/mach-visws/mach_apicdef.h to the generic version.
This should work fine as VISWS has a standard local APIC and thus
its mach_apicdef.h copy is just an ancient version of the generic code.

now that include/asm-x86/mach-visws/smpboot_hooks.h equals
to the default file in ../mach-default/smpboot_hooks.h, simply
include it instead of maintaining a copy.

update include/asm-x86/mach-visws/smpboot_hooks.h to
include/asm-x86/mach-default/smpboot_hooks.h (the generic version).
this _should_ work, because VISWS sets skip_ioapic_setup, but it
should be tested on a real VISWS to make sure.

mach-default/entry_arch.h is exactly the same file as
mach-visws/entry_arch.h, so include the first from the second,
so that updates to the generic one get picked up by VISWS as well.

fix:
arch/x86/kernel/built-in.o: In function `smp_intr_init':
(.init.text+0x49e2): undefined reference to `call_function_single_interrupt'
Caused by include/asm-x86/mach-visws/entry_arch.h getting out of sync
with the include/asm-x86/mach-default/entry_arch.h file it derives from.
Copy the default file over - next step will be to simply include the default
file.

x86_64 has two nr_ioapics = 0 statements. In 32-bit, it can be done
too. We do it through the smpboot_clear_io_apic() inline function,
