Subject: [PATCH v2 1/3] x86/amd_nb: Add PCI IDs for AMD Family 1Ah-based models

From: Avadhut Naik <Avadhut.Naik@....com>

Add new PCI Device IDs, required to support AMD's new Family 1Ah-based
models 00h-1Fh, 20h and 40h-4Fh.

Since, models 40h-4Fh and model 20h share some design aspects, the PCI
IDs defined in this patch for model 20h are shared by models 40h-4Fh.
