ASoC: dsp: Update dap driver to support Instance ID

Add support to set and get dap modules params with
Instance ID support for both Dolby and DS2.
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.
