Any Juno board should be fine as that has a SMMUv1. Once in LSK, we can test it is still ok on a v2 part.

Will – are there some tests (LTP?) that can be used to test it is working ok when back ported?

Nope; there are no in-tree users of the ARM SMMU, mainly due to lack of IOMMU-backed DMA ops for arm64 (patches are in review stage atm).

You could have a play with VFIO, but you'll need userspace support and working PCI for that.
