I can not understand this: what kind of features are so different that
you can not include them into a single firmware image? Please enable all
users with all possible features instead of tying them to a product
segment. If I'm missing something, please provide additional
information.

Why do you need even more nesting for IoT products? "qca/iot/ROME/QCA6390"
also looks strange, but perfectly possible with your patch

Without the IoT platform you can just include a static string.

No need to describe regulators, use PMU and powerseq.

Why can't you use the qca_soc_data_wcn6855?

Completely unrelated, cleanups go to a separate patch.

Don't spam users with useless hex numbers. Printing the sensible string
should be fine though.
