The ARM64 ACPI NUMA code can be moved out of arm64 arch code
as it just related to ACPI NUMA table parsing, mappings for
ACPI NUMA and cpu, move the ACPI NUMA code to drivers/acpi/arm64/.

Since arm64 selects ACPI_NUMA by default, so just move the function
definitions under CONFIG_ARM64 in linux/acpi.h.
