If there are no consumers, should we just not add and deal with it
entirely within the kernel. I know we rely today on presence of node
before we initialise, but hey we have exception for system power protocol
for other reasons, why not add this one too.

In short we shouldn't have to add a node if there are no consumers. It
was one of the topic of discussion initially when SCMI binding was added
and they exist only for the consumers otherwise we don't need it as
everything is discoverable from the interface.
