mmc: jz4740: add dma infrastructure for data transfers Until now the MMC driver for JZ4740 SoC was relying on PIO mode only for data transfers. This patch allows the use of DMA for data trasnfers in addition to PIO mode by relying on DMA Engine. DMA tranfers performance might be further improved by taking advantage of the asynchronous request capability of the MMC framework.
