nouveau: Possible VGA switcheroo problem fix

If this is exactly the same issue as in bug #61891, this (untested) patch on top of

https://patchwork.kernel.org/patch/3414401/

should work for nouveau.

I could test it after a struggle. This is what I did:

Patched the clean 3.13rc5 tarball with both patches and compiled it. After that adding the "acpiphp.disable=1" workarround made no difference, so that issue might be cleared.

That's what the patch is for, so it looks like it has worked.

I'll the nouveau workaround to https://patchwork.kernel.org/patch/3414401/ then.
