move the include/asm-x86/mach-visws/ VISWS specific hardware
details include files into include/asm-x86/visws, to be used from
generic code.

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.

x86_64 has two nr_ioapics = 0 statements. In 32-bit, it can be done
