arc: fix arc_dma_sync_sg_for_{cpu,device}
These functions should perform the same functionality as calling arc_dma_sync_single_for_{cpu,device} on each S/G list element. Ensure they actually do that by calling arc_dma_sync_single_for_{cpu,device}. Otherwise we could be passing a different dir argument.
