Not 100% perfect yet, but a good start towards what it'll look like in the
end.
Actually seems stable on a NV44 I have here, as much as running around OA
for a fair amount of time constantly switching between performance levels
can prove..
My NV49 isn't quite so happy, and semaphores mess up somehow (sometimes) as
a result of the memory reclocking.

Not too certain on memory clock yet, but it gets the right numbers for
each perflvl on my NVC0.

This will end up quite different, it makes sense for it to be completely
separate.

On certain boards, there's BIOS scripts and memory timings that need to
be modified with the memclk. Just pass in the entire perflvl struct and
let the chipset-specific code decide what to do.

This isn't correct everywhere yet, but since we don't use the data yet
it's perfectly safe to push in, and the information we gain from logs
will help to fix the remaining issues.
v2 (Ben Skeggs <bskeggs@redhat.com>):
- fixed up formatting
- free parsed timing info on takedown
- switched timing table printout to debug loglevel

Currently just hooked up to the already-existing nouveau_hw, which should
handle all relevant chipsets as well as we currently can.
This will likely be eventually split out and improved into chipset specific
code at a later point.

This will make nouveau_pm attempt to report the card's current performance
level both during bootup, and through sysfs.
This is a very initial implementation, and can be improved a *lot*
