iommu/arm-smmu: Don't register fwnode for legacy binding
When using the legacy binding we bypass the of_xlate mechanism, so avoid registering the instance fwnodes which act as keys for that. This will help __iommu_probe_device() to retrieve the registered ops the same way as for x86 etc. when no fwspec has previously been set up by of_xlate.
