The protocol@13 node is describing the performance scaling option for the
ARM SCMI interface, as a clock provider. This is unnecessary limiting, as
performance scaling is in many cases not limited to switching a clock's
frequency.
Therefore, let's extend the binding so the interface can be modelled as a
generic "performance domain" too. The common way to describe this, is to
use the "power-domain" bindings, so let's use that.
