dmaengine: mv_xor: Enlarge descriptor pool size
Now that we have 2 channels assigned to 2 CPUs and all requests are chained on same channels, we need much more descriptors available to satisfy async_tx workload. 3072 descriptors was found in our lab as the number of descriptors which allow the async_tx stack to work without waiting for free descriptors on submission of new requests.
