Liam Girdwood 8a9782346d ASoC: topology: Add topology core
The topology core parses the FW topology file for known block types and
instanciates any common ALSA/ASoC objects that it discovers. The core
also passes any block that is does not understand to client component
drivers for enumeration.

The core exports some APIs to client drivers in order to load and unload
firmware topology data as use case require.

Currently the core deals with the following object types :-

 o kcontrols. This includes TLV, enumerated and bytes controls.
 o DAPM widgets. All types with any associated kcontrol.
 o DAPM graph.
 o FE PCM. FE PCM capabilities and configuration can be defined.
 o BE DAI Link. BE DAI link capabilities and configuration can be defined.
 o Codec <-> codec style links capabilities and configuration.
