ASoC: tegra-alt: ADSP driver enhancements

Browse Source 
1. Fix ADSP crash due to reorder of mixer commands
2. Add support to track the PCM paths constructed, have a
   record of FE/BE connections made by the user.
3. Support ADSP pipeline breakage, linkage, modifications
4. Plugin params can be set at any time

This change depends on http://git-master/r/#/c/709103/
functionality wise.
