sparc: Use asm-generic/pci-dma-compat

Browse Source 
This converts SPARC to use asm-generic/pci-dma-compat instead
of the homegrown mechnism.

SPARC32 has two dma_map_ops structures for pci and sbus
(removing arch/sparc/kernel/dma.c, PCI and SBUS DMA accessor).
The global 'dma_ops' is set to sbus_dma_ops and get_dma_ops()
returns pci32_dma_ops for pci devices so we can use the
appropriate dma mapping operations.
