Thanks Daniel.

It looks like your hostbridge zero device has a different device id
than in my first generation Ryzen system.  Would you please try the
following patch and see if it attaches on your system?  I don't
actually have documentation for Ryzen 2, unfortunately, so I'm not
totally sure if the SMN is accessed in the same way for the new
hostbridge device id.  The change below should at least attempt
attaching to hostb0 on your system.
