For the legacy smmuv3 test case, generated IORT has a single SMMUv3 node,
a Root Complex(RC) node and 1 ITS node.
RC node features 4 ID mappings, of which 2 points to SMMU node and the
remaining ones points to ITS.
pcie.0 -> {SMMU0} -> {ITS}
{RC} pcie.1 -> {SMMU0} -> {ITS}
pcie.2 -> {ITS}
[all other ids] -> {ITS}
