[patch V6 10/19] x86/smpboot: Teach it about topo.amd_node_id

[Thomas Gleixner <tglx@linutronix.de>]

From: Thomas Gleixner <tglx@linutronix.de>

When switching AMD over to the new topology parser then the match functions
need to look for AMD systems with the extended topology feature at the new
topo.amd_node_id member which is then holding the node id information.
