ASoC: Intel: Skylake: Add table for module id for quick ref

Browse Source 
Since modules ids are generated dynamically, we do not know the id
associate with modules in another pipelines. This limits our ability to
tell DSP about neighbouring modules.

So add a table for quick referencing of allocated module ids.
