Subject: [PATCH 1/2] dt-bindings: clock: rk3576: add SCMI clocks

Mainline Linux uses different clock IDs from both downstream and
mainline TF-A, which both got them from downstream Linux. If we want to
control clocks through SCMI, we'll need to know about these IDs.

Add the relevant ones prefixed with SCMI_ to the header.
