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

Signed-off-by: Guenter Roeck <linux@roeck-us.net>

This patch is a prerequisite for the second patch in the series.
I'll be happy to apply both patches through hwmon if that is acceptable
(and Cc: stable for 4.16+). If not, I'll be happy to wait for this patch
to be available upstream.

Since that there is no public documentation available for Raven Ridge,
PCI IDs are derived from output of lspci.
