Ashish Mhetre ff7d0cc87c platform: tegra: rtcpu: Fix cache sync APIs ...

For dma mappings done with dma_map_sg() calls, dma_sync_sg* calls are
required in order to make sure that caches for all the scattered
addresses are synced. Using dma_sync_single* call for syncing caches
can access address which is not mapped by dma_sync_sg() and cause kernel
exceptions.
Fix this by using correct cache sync calls for appropriate dma mapping
APIs.
