PPC: KVM: Update HIOR code to new interface
Unfortunately the HIOR setting code slipped into upstream QEMU before it was pulled into upstream KVM. And since Murphy is always right, comments on the patches only emerged on the pull request leading to changes in the interface. So here's an update to the HIOR setting. While at it, I also relaxed it a bit since for HV KVM we can already run fine without and 3.2 works just fine with HV KVM but when not setting HIOR. We will only need this when running PAPR in PR KVM. Since we accidently changed the ABI and API along the way, we have to update the underlying kernel headers together with the code that uses it to not break bisectability.
