Re: [PATCH v2 2/2] virtio: Document DMA coherency

Since making use of the DMA API will require the architecture code to
have the correct notion of device cache-coherency on architectures like
ARM, explicitly call this out in the virtio-mmio DT binding. The ship
has sailed for legacy virtio, but let's hope that we can head off any
future firmware mishaps.
