commit 2bb9f7566ba7ab3c2154964461e37b52cdc6b91b upstream.

Since ceeeb99cd821 we no longer abuse the DMA_CTRL_ACK flag for custom
driver use and introduced the MXS_DMA_CTRL_WAIT4END instead. We have not
changed all users to this flag though. This patch fixes it for the
mxs-mmc driver.

Fixes: ceeeb99cd821 ("dmaengine: mxs: rename custom flag")
