Replace dmac_inv_range and dmac_clean_range functions with the new dma map and unmap functions. These are supposed to be the new functions to do the same functionality, but in our limited testing some time ago, the dma_unmap function wasn't invalidating the cache. You can check this at your end. 2. Revert the patch that deprecated these APIs to unblock you temporarily.
