On newer heterogeneous systems with AMD CPUs the data fabrics of GPUs
can be connected directly via custom links.

This series of patchset does the following
1. amd_nb.c:
   a. Add support for northbridges on Aldebaran GPU nodes
   b. export AMD node map details to be used by edac and mce modules
	
2. mce_amd module:
   a. Identify the node ID where the error occurred and map the node
      id to linux enumerated node id.

3. amd64_edac module
   a. Add new family op routines
   b. Enumerate UMCs and HBMs on the GPU nodes
   c. Move fam_type structure into amd64_pvt struct

This patchset is rebased on top of
