Subject: [PATCH 2/2] Blackfin: fix dma-mapping build errors

The recent deprecation of dma_sync_{sg,single} ironically broke Blackfin
systems.  This is because we don't define dma_sync_sg_for_cpu at all, so
until the DMA asm-generic conversion/cleanup is done after the next
release, simply redirect the dma_sync_sg_for_cpu to the debug version.
