SPARSEMEM is the only possible memory model for x86-64, FLATMEM is not
possible:
	config ARCH_FLATMEM_ENABLE
		def_bool y
		depends on X86_32 && !NUMA

And X86_64_ACPI_NUMA (obviously) only supports x86-64:
	config X86_64_ACPI_NUMA
		def_bool y
		depends on X86_64 && NUMA && ACPI && PCI

Let's just remove the CONFIG_X86_64_ACPI_NUMA dependency, as it does no
longer make sense.
