sparc: Add CONFIG_DMA_API_DEBUG support
All we need to do for CONFIG_DMA_API_DEBUG support is call dma_debug_init() in DMA code common for SPARC32 and SPARC64. Now SPARC32 uses two dma_map_ops structures for pci and sbus so there is not much dma stuff for SPARC32 in kernel/dma.c. kernel/ioport.c also includes dma stuff for SPARC32. So let's put all the dma stuff for SPARC32 in kernel/ioport.c and make kernel/dma.c common for SPARC32 and SPARC64.
