IMO, we need both, and this enum still belongs in the firmware header.
We have two separate things, the firmware interface and the DT
interface. The kernel is a consumer for both, but the fact that they
match is an implementation detail. It might even change in the future
for all we know.

So having a header to use defines for the clock indices in the DT looks
like a good idea to me, but I think we should keep that enum in the
firmware header as well.
