From: Mengdong Lin <mengdong.lin@linux.intel.com>

Pump ABI version to 5.

To support physical DAIs and furture extension, add the following fields
to manifest:
- the count of physical DAIs. Later patches will add new ABI types for
  physical DAIs.
- some reserved fields for new ABI objects in the future.

Kerel will handle this ABI update in a backward compatible way, via patch
'ASoC: topology: Make manifest backward compatible from ABI v4'.

Signed-off-by: Mengdong Lin <mengdong.lin@linux.intel.com>
