This changeset adds the necessary changes for running GCN3 ISA with VIPER in apu_se.py. Changes to the VIPER protocol configs are made to add support for DMA and scalar caches. hsaTopology is added to help the pseudo FS create the files needed by ROCm to understand the device on which the SW is being run.
