No.. the PIR itself is a cpu level construct (and we already have a
place for that in the cpu state). The DT id as such isn't, although
it happens to have the same value. The fact it has the same value is
itself a machine type property.
[Aside: removing dt_id from the cpu will require disentangling it from
the kvm vcpu id]
