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.

changes in v2:
 - rebase on asoc-next
 - fix some typo
 - compare and merge Kuninori Morimoto's version
 - add warning if the function is not support multi cpu yet

Bard liao (1):
  ASoC: add warning if the function is not support multi cpu yet.

Shreyas NC (3):
  ASoC: Add initial support for multiple CPU DAIs
  ASoC: Add multiple CPU DAI support for PCM ops
  ASoC: Add multiple CPU DAI support in DAPM
