Guo Ren ae76f635d4 csky: Optimize arch_sync_dma_for_cpu/device with dma_inv_range ... DMA_FROM_DEVICE only need to read dma data of memory into CPU cache, so there is no need to clear cache before. Also clear + inv for DMA_FROM_DEVICE won't cause problem, because the memory range for dma won't be touched by software during dma working. Changes for V2: - Remove clr cache and ignore the DMA_TO_DEVICE in _for_cpu. - Change inv to wbinv cache with DMA_FROM_DEVICE in _for_device.
