> Usually dma_supported decisions are done by the dma_map_ops instance.
> Switch sparc to that model by providing a ->dma_supported instance for
> sbus that always returns false, and implementations tailored to the sun4u
> and sun4v cases for sparc64, and leave it unimplemented for PCI on
> sparc32, which means always supported.
