dma-controller is covered by dma-controller.yaml, which references
dma-common.yaml in its entirety, so I don't think that would work.

What about "blitter"? I think that is a generic term that is/was commonly
used with display hardware and sort of describes the function of the RDMA
& WDMA blocks, and if only one side is memory and the other is the display
pipeline.
