I think it really needs a cpuid feature bit for the hwpstate.  This is
not in one of the normal CPUID leaves, so the amd specific CPU init
code would need to set it.

I added 0x15 for now, but it would be good if someone with the hardware
fixed it like this.

Then could just add a match on "AMD-hw pstate" or so.
