acpi_numa_arch_fixup() is only used for IA64, x86 introduce a dummy
function for it, when we came to a new architecture (such as ARM64),
we need to introduce another dummy one to make the code compile.

That's pretty boring so introduce ACPI_HAS_NUMA_ARCH_FIXUP and
select it for IA64, introduce a stub function for acpi_numa_arch_fixup()
then it's pretty clean for x86 and ARM64.

I see an implementation of acpi_numa_arch_fixup() only for ia64. Why
not move it to arch/ia64 then and call it from setup_arch() in
arch/ia64/kernel/setup.c after acpi_numa_init()? It looks like we
don't need a generic solution for this. This avoids any kconfig
handling for this at all.

It's much simpler as you suggested, I will update it in next
version, thank you Robert :)
