[PATCH v2 01/13] hw/sd/sdhci: Set SDHC_NIS_DMA bit when appropriate

[Bernhard Beschow]

In U-Boot, the fsl_esdhc[_imx] driver waits for both "transmit completed" and
"DMA" bits in esdhc_send_cmd_common() by means of DATA_COMPLETE constant. QEMU
currently misses to set the DMA bit which causes the driver to loop forever. Fix
that by setting the DMA bit if enabled when doing DMA block transfers.
