topology: ABI - Update stream caps and PCM objects to ABI v5
topology: ABI - Update stream caps and PCM objects to ABI v5

Here are the ABI updates for PCM (Front DAI & DAI link) objects:

- add sig_bits to stream caps.
- add flags and private data to PCM.

The kernel can handle the ABI update in a backward compatible way with
the patch "ASoC: topology: Make PCM backward compatible from ABI v4".
