I did not introduce a subtype, only a subclass. But we could
possibly. It seemed overkill for one attribute.

I would also prefer to move the compat string to PnvPsiClass instead
of using a chip_type field but I didn't find a clean way for it. We
use sizeof() on the compat string below and it does not work on a
char *.
I had the same issue in pnv_dt_xscom()

Well, in this case, I think we could put 'psi->regs[reg] = val;'.
