Subject: [PATCH] x86: add PCI IDs to k8topology_64.c

Quick history, this is a harmless patch that got dropped by Andi as a mixup to 
dropping another patch of mine that was made obsolete by Yinghai.

    x86: add PCI IDs to k8topology_64.c
    
    This just adds the PCI IDs of AMD's family 10h and 11h CPU's northbridges 
to
    k8topology discovery.
