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 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.
Bard liao (1): ASoC: return error 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
