Add a driver to VFIO selftests for Intel DSA devices. For now the driver only supports up to 32 batches and 1024 copies per batch, which were the limits of the hardware this commit was tested with. This is sufficient to generate 9+ minutes of DMA memcpys at a rate of over 30 GB/s. This should be plenty to stress test VFIO and the IOMMU. The driver does not yet support requesting interrupt handles, as this commit was not tested against hardware that requires it.
