memif: support dma option
Introduce async model into memif by utilizing new DMA API. Original process is broken down to submission stage and completion stage. As multiple submissions may in flight simultaneously, per thread data is no longer safe, now replace thread data into each dma data structure. As slave side already support zero copy mode, DMA option is only added in master side.
