ASoC: topology: Add support for BE DAIs

From: Mengdong Lin <[email protected]>

There is topology ABI udpate in this series. Topology core can check size of each ABI objects to detect version mismatch between user space and kernel.

This series adds support for BE (Back End) DAIs:
- Define the type and ABI struct for Backend DAIs.
- The topology core can configure an existing BE DAI or create new BE DAIs.

The user space series "topology: Add support for BE DAIs" is also submitted.

Is it possible to meet the timeline of v4.8?
There will be 2 pairs of kernel & user space series for PCM & BE links later.

ASoC: topology: ABI - Add the types for BE DAI
ASoC: topology: Add support for configuring existing BE DAIs
ASoC: topology: Able to create BE DAIs
