tools/power turbosat: fix AMD APIC-id output
turbostat recently gained a feature adding APIC and X2APIC columns. While they are disabled by-default, they are enabled with --debug or when explicitly requested, eg. $ sudo turbostat --quiet --show Package,Node,Core,CPU,APIC,X2APIC date But these columns erroneously showed zeros on AMD hardware. This patch corrects the APIC and X2APIC [sic] columns on AMD. Signed-off-by: Len Brown <len.brown@intel.com>
