Alexander Graf f2e91042a8 KVM: PPC: Add CAP to indicate hcall fixes
We worked around some nasty KVM magic page hcall breakages:

  1) NX bit not honored, so ignore NX when we detect it
  2) LE guests swizzle hypercall instruction

Without these fixes in place, there's no way it would make sense to expose kvm
hypercalls to a guest. Chances are immensely high it would trip over and break.

So add a new CAP that gives user space a hint that we have workarounds for the
bugs above in place. It can use those as hint to disable PV hypercalls when
the guest CPU is anything POWER7 or higher and the host does not have fixes
in place.
