The commit messages mention sc8280xp having 13 power domains, but here I
only count 12. Good chance I'm just missing something obvious (not
familiar with using power domains or rpmh) but I thought I should
highlight it in case that was an error.
I attempted to find where this sort of thing is defined downstream, but
failed :(
Thanks,
Andrew
