hw/arm/virt: Default to two-stage SMMU from virt-9.2
Now that our SMMU model supports enabling both stages of translation at once, we can enable this in the virt board. This is no change in behaviour for guests, because if they simply ignore stage 2 and never configure it then it has no effect. For the usual backwards compatibility reasons we enable this only for machine types starting with 9.2. (Note that the SMMU is disabled by default on the virt board and is only created if the user passes the 'iommu=smmuv3' machine option.)
