gpu: nova-core: set DMA mask width based on GPU architecture

Replace the hardcoded 47-bit DMA mask with a GPU HAL method that
provides the correct value for the architecture.

Set the DMA mask in Gpu::new(). Gpu owns all DMA allocations for
the device, so no concurrent allocations can exist while the
constructor is still running.
