octeontx2-af: Fix memory scaling limitation in SR-IOV mode
The original code used DMA_ATTR_FORCE_CONTIGUOUS, which could exhaust
the CMA pool when a large number of VFs were requested.
Fix this by switching to the DMA streaming API. This is equivalent on
Octeon platforms, which provide full I/O coherency via the SMMU.
