No need for that, the path I'm suggesting is located under
arch/arm/include/asm/mach, it's not same as include <mach/dma-omap.h>.

No need for splitting anything :)

The other possible location would be just include <linux/dma-omap.h>,
but as we all know that will be going away, <asm/mach/dma-omap.h>
is probably better.
