dma-mapping: mark dma_sync_single and dma_sync_sg as deprecated 

dma_sync_single() and dma_sync_sg() have been described as "Backwards
compat, remove in 2.7.x" for a long time (since 2.6.5).

This marks dma_sync_single() and dma_sync_sg() as deprecated so the users
get notified before removing them.
