For the legacy SMMUv3 test, the setup includes three PCIe Root Complexes,
one of which has bypass_iommu enabled. The generated IORT table contains
a single SMMUv3 node and a Root Complex node with three ID mappings. Two
of these ID mappings have output references pointing to the SMMUv3 node
and the remianing one points to ITS.
For the -device arm-smmuv3,... test, the configuration also includes three
Root Complexes, with two connected to separate SMMUv3 devices.
The resulting IORT table contains two SMMUv3 nodes and a Root Complex node
with ID mappings of which two of the ID mappings have output references
pointing to two different SMMUv3 nodes and the remaining ones to ITS.
