GPU_SMMU SID 1 is meant for Adreno LPAC (Low Priority Async Compute). On platforms that support it (in firmware), it is necessary to describe that link, or Adreno register access will hang the board. The current settings are functionally identical, *but* due to what is likely hardcoded security policies, the secure firmware rejects them, resulting in the board hanging. To avoid that, alter the settings such that SID 0 and 1 are described separately.
