This commit breaks build of the (hopefully) soon to-be-merged mx2_camera driver.
This driver is for both mx25 and mx27. Since dma-mx1-mx2.h is now under the
non-mx25 mach-imx/ directory, mx25 build can't find this header.

The solution is either:

1. move mx25 to mach-imx/ as well, or

2. postpone the dma-mx1-mx2.h header move for now, and leave it under plat-mxc/

Any thoughts?
