[PATCH v7 04/15] acpi, numa: Move acpi_numa_arch_fixup() to ia64 only

From: Robert Richter <rrichter@cavium.com>

Since acpi_numa_arch_fixup() is only used in arch ia64, move it there
to make a generic interface easier. This avoids empty function stubs
or some complex kconfig options for x86 and arm64.
