I already added this and various other PMUv3.9 registers you've added 
here in v6.12 and v6.13. So are you on an old base or the tool allows 
multiple definitions? If the latter, that should be fixed.

We're never going to use Pnn defines. This is just useless bloat unless 
we're aiming to top amd gpu defines LOC.
