MA-14108 Avoid flush cache when map/umap noncacheable dma buffer for ION dma_map_sg will call flush cache when map noncacheable dma buffer. Add DMA_ATTR_SKIP_CPU_SYNC to skip flush cache to reduce cpu loading. ION alloc will pass flag ION_FLAG_CACHED if the buffer need read or write by cpu, then don't skip flush cache.
