TBH, I considered getting rid of all the macros and just use something
like 300 * MHZ.
Another alternative is to encode the clock rate in struct hantro_variant
itself.
In any case, I don't see this adding any value, so maybe I'll
just reuse rk3036_vpu_hw_init as you suggest.

Ah, this slipped through. You are right of course.
