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.
