The existing code partitioning makes limited sense, the capabilities are parsed at the sound/hda level but helpers are located in sound/hda/ext. This patch moves all the SPIB/DRMS functionality to the sound/hda layer. This reduces the complexity of the sound/hda/ext layer which is now limited to handling the multi-link extensions and stream coupling/decoupling helpers. Note that this is an iso-functionality code move and rename, the HDaudio legacy driver would need additional changes to make use of these capabilities.
