sparc: use generic dma_set_mask
Sparc already uses the same code as the generic code for the PCI implementation but just fails the call sbus. This moves to the generic implemenation which eventually return -EIO due to the NULL dma_mask pointer in the device. Signed-off-by: Christoph Hellwig <hch@lst.de> Cc: "David S.
