Add support to set and get rtac params with
Instance ID support. Maintain support for non
Instance ID set and get param structures as well.
Use common pack and set param functions to set and
get parameters to DSP instead of handling them at an
individual module level.

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.
