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

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.
