iommu: store DT-probed IOMMU data privately
Since the data pointer in the DT node is public and may be overwritten by conflicting code, move the DT-probed IOMMU ops to a private list where they will be safe. Acked-by: Grant Likely <grant.likely@linaro.org> Signed-off-by: Robin Murphy <robin.murphy@arm.com> [will: added missing #include and missing ')'] Signed-off-by: Will Deacon <will.deacon@arm.com>
