Subject: [PATCH V3 3/3] PCI: Remove unnecessary 'quirk_amd_nb_node'

From: Myron Stowe <myron.stowe@...hat.com>

The quirk is used for fixing up the numa_node information in sysfs for AMD hostbridge
devices (i.e. PCI device 00:[18-1f].x).  However, this is currently unused.
and is becoming maintenance burden. Therefore, it is removed.
