The shipping version is v2.1 and you defined the 660.1 chipid,
which maps to lahaina(>=v2)
Yes, let's drop these comments.

Shouldn't this one belong to the smmu?
The vendor kernel lists it both for the smmu and the gpu. SC7280 also
lists it for both devices. I'll take a look at the smmu clocks for the v2.
