Pull misc x86 updates from Borislav Petkov:

 - The first part of a restructuring of AMD's representation of a
   northbridge which is legacy now, and the creation of the new AMD node
   concept which represents the Zen architecture of having a collection
   of I/O devices within an SoC. Those nodes comprise the so-called data
   fabric on Zen.

   This has at least one practical advantage of not having to add a PCI
   ID each time a new data fabric PCI device releases. Eventually, the
   lot more uniform provider of data fabric functionality amd_node.c
   will be used by all the drivers which need it

 - Smaller cleanups
