[PATCH v3 1/6] xen/x86: Provide helpers for common code to access acpi_numa

acpi_numa is a specific NUMA switch for ACPI NUMA implementation. Other NUMA implementation may not need this switch. But this switch is not only used by ACPI code, it is also used directly in some general NUMA logic code. So far this hasn't caused any problem because Xen only has x86 implementing
