[PATCH] mmc mxcmmc: fix falling back to PIO

When we can't configure the dma channel we want to fall back to PIO. We do this by setting host->do_dma to zero. This does not work as do_dma is used to see whether dma can be used for the current transfer. Instead, we have to set host->dma to NULL. Signed-off-by: Sascha Hauer Cc: Chris Ball Cc:
