As discussed in [1], ASoC core supports multi codec DAIs
on a DAI link. However it does not do so for CPU DAIs.
So, add support for multi CPU DAIs on a DAI Link by adding
multi CPU DAI in Card instantiation, suspend and resume
functions, PCM ops, stream handling functions and DAPM.
[1]: https://www.spinics.net/lists/alsa-devel/msg71369.html
changes in v3:
- Return error if the function doesn't support multi cpu instead of
just showing a warning message.
- Revert changes for FE dai and compress device since we don't support
multi cpu for FE dai and compress device yet.
The code looks mostly good, except for an error in soc-compress (patch 4).
I would still suggest refactoring code first, adding the new checks or
helpers first, to make sure we have the same functionality before adding
the multi-cpu-dais, see specific points in the other emails.
Thanks Bard and Morimoto-san.
