Subject: [PATCH v1] x86/amd_nb: Add new PCI IDs for AMD family 0x1a model 60h

Add the new PCI Device IDs to the root IDs and misc ids list to support
new generation of AMD 1Ah family 60h Models of processors.

Signed-off-by: Shyam Sundar S K <Shyam-sundar.S-k@....com>

(As the amd_nb functions are used by PMC and PMF drivers, without these IDs
being present AMD PMF/PMC probe shall fail.)
