From: Greg Kurz <groug@kaod.org>

The sPAPR XIVE device is created by the machine in spapr_irq_init().
The latter overrides any value provided by the user with -global for
the "nr-irqs" and "nr-ends" properties with strictly positive values.

It seems reasonable to assume these properties should never be 0,
which wouldn't make much sense by the way.
