ACPI / NUMA: move acpi_numa_slit_init() to drivers/acpi/numa.c
Identical implementations of acpi_numa_slit_init() are used by both x86 and follow-on arm64 support. Move it to drivers/acpi/numa.c, and guard with CONFIG_X86 || CONFIG_ARM64 because ia64 has its own architecture specific implementation. No code change.
