    IIUC, because the only 2 file using it were under arch/arm/mach-shmobile/.

    Phil's patches were only for R8A7778, IIRC (yet, the platfrom DMA code was 
placed in a separate file, not r8a7778.c). Max decided to use the 
<mach/hpb-dmae.h> header for sharing the DMA channel IDs between R8A777[89], I 
agreed but suggested to use the empty <mach/dma.h> instead.
