Why is this a separate compilation unit and not part of amd_node.c? Especially
if it depends on it.
I don't see the real need for having smaller compilation units. Both the node
and the smn stuff will end up being built-in in 99% of the configs. So why are
we making separate Kconfig items and yadda yadda?
Just do a single amd_node and that's it. We can always split later, if really
needed.
