[Freedreno] [PATCH 19/20] iommu/arm-smmu: add a way for implementations to influence SCTLR

From: Rob Clark For the Adreno GPU's SMMU, we want SCTLR.HUPCF set to ensure that pending translations are not terminated on iova fault. Otherwise a terminated CP read could hang the GPU by returning invalid command-stream data. Signed-off-by: Rob Clark --- drivers/iommu/arm/arm-smmu/arm-smmu
