Remove the duplicate dmaVirt calls from HSA packet processor and GPU command processor and move them into their own class. This removes some duplicate code and allows a DmaVirtDevice to be created which will be useful for upcoming full system GPU commits. The DmaVirtDevice is an abstraction of the base DmaDevice but iterates using ChunkGenerator over virtual addresses. Classes which inherit from DmaVirtDevice must provide a translation function to translate from virtual address to physical address. Once translated, the physical address is passed to DmaDevice to do the work.
