From: Mengdong Lin <mengdong.lin@xxxxxxxxxxxxxxx>
Add the following fields to manifest:
- a count of physical DAIs. Later patches will add new ABI types for
physical DAIs.
- some reserved fields for future extenstion.
Pump ABI version to 5.
Kerel will handle this ABI update in a backward compatible way, via patch
'ASoC: topology: Make manifest backward compatible from ABI v4'.
