Tony Luck 6f6947b238 x86/resctrl: Only check Intel systems for SNC ...

topology_num_nodes_per_package() reports values greater than one on certain
AMD systems resulting in resctrl's Intel model specific SNC detection
printing the confusing message:

   "CoD enabled system? Resctrl not supported"

Add a check for Intel systems before looking at the topology.
