New topology ripped from Fiji to support dGPU. A dGPU flag is added to the config which is propogated to the driver. The emulated driver is now able to properly deal with dGPU ioctls and mmaps. For now, dGPU physical memory is allocated from the host, but this is easy to change once we get a GPU memory controller up and running.
