sparc: remove arch specific dma_supported implementations
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.
