[PATCH v2 0/5] iommu/arm-smmu-v3: Fixes reported by Sashiko

[Mostafa Saleh <smostafa@google.com>]

While running sashiko locally on the pKVM SMMUv3 driver patches, it
reported some pre-existing issues in the SMMUv3 driver (the RB tree
corruption and a missing NULL check) and given that this is not the
first time a pre-existing issue appears in the driver from sashiko,
I went ahead and passed the whole driver to Sashiko which reported a
dozen of other issues(except the last one in this series), I included
fixes for bugs I believe are true or worth fixing (others were mostly
missing NULL checks or bizarre HW/FW configs I don't think are needed).

I also sorted the patches based on severity from the most critical to
the least, so it is easier to apply a prefix if some bugs are too
theoretical

Changes in v2:
v1: https://lore.kernel.org/all/20260828125409.1921538-1-smostafa@google.com/
- Drop patches 2 and 3 as they are fixed by other patches on the list
- Collect Rbs
