Put in a more accessible place the reasoning behind our decision
to officially drop KVM support in the powernv machine.

+Current acceleration status
+---------------------------
+
+KVM acceleration in Linux Power hosts is provided by the kvm-hv and
+kvm-pr modules. kvm-hv is adherent to PAPR and it's not compliant with
+powernv. kvm-pr in theory could be used as a valid accel option but
+this isn't supported by kvm-pr at this moment.
+
+To spare users from dealing with not so informative errors when attempting
+to use accel=kvm, the powernv machine will throw an error informing that
+KVM is not supported. This can be revisited in the future if kvm-pr (or
+any other KVM alternative) is usable as KVM accel for this machine.
