Between Linux-4.9 and Linux-4.14, upstream has updated the ION APIs significantly to make ION ready to bring out of staging folder. This has changed the way ION and dma_buf APIs used to work together for allocating, mapping and deallocating ION buffers. Update MSM Audio ION wrapper functions used by audio drivers to reflect these ION API changes as per upstream ION.
