Now that our SMMU model supports enabling both stages of translation
at once, we can enable this in the sbsa-ref board. Existing guest
code that only programs stage 1 and doesn't care about stage 2 should
continue to run with the same behaviour, but guests that do want to
do nested SMMU configurations can now do so.
