I'd have hoped that for information on firmware we'd be keying off
descriptive information included in the firmware/topology itself,
ideally the kernel would be able to do that itself.

You definitely shouldn't be doing that, but I'd also not expect us to
have to update anything that isn't the firmware itself.
