dma: imx-dma: Fix build by including <linux/module.h>

commit 13ae246 (includecheck: delete any duplicate instances of module.) removed a duplicated module.h inclusion from imx-dma.c.

,and commit 865d9438 (drivers/dma: linux/module.h included twice) did the same.

Let one linux/module.h be included so that it can be built again.

This fix the following error:
