Subject: [PATCH v3 1/2] x86/amd_nb: Add support for Raven Ridge CPUs

Add Raven Ridge root bridge and data fabric PCI IDs.
This is required for amd_pci_dev_to_node_id() and amd_smn_read().

Tested-by: Gabriel Craciunescu <nix.or.die@...il.com>
Signed-off-by: Guenter Roeck <linux@...ck-us.net>

v3: No change.
v2: Use naming scheme suggested by Borislav Petkov.
