Robin Murphy dc98b8480d iommu/exynos: Don't unconditionally steal bus ops ... Removing the early device registration hook overlooked the fact that it only ran conditionally on a compatible device being present in the DT. With exynos_iommu_init() now running as an unconditional initcall, problems arise on non-Exynos systems when other IOMMU drivers find themselves unable to install their ops on the platform bus, or at worst the Exynos ops get called with someone else's domain and all hell breaks loose. The global ops/cache setup could probably all now be triggered from the first IOMMU probe, as with dma_dev assigment, but for the time being the simplest fix is to resurrect the logic from commit a7b67cd5d9 ("iommu/exynos: Play nice in multi-platform builds") to explicitly check the DT for the presence of an Exynos IOMMU before trying anything.
