Missing commit msg.

A nit, subject: drop second/last, redundant "bindings". The
"dt-bindings" prefix is already stating that these are bindings.

Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching. For bindings, the preferred subjects are
explained here:

This is supposed to be part of bindings adding the clock controller.

Drop all (). Not needed, not useful.

IDs cannot be reserved. It is a binding, not a hardware number.

No drop. Others as well.
