configs: Handle various DMA devices in GPU_VIPER
Viper is checking for the dma's type before making the port assignment.
In FullSystem mode the IDE device is a PortRef and does not have an
attribute 'type.' This handles the various types a bit better and
ensures that IDE device, the protocol tester, and upcoming DMA devices
related to FullSystem can be added.
