audio card disappeared after suspend device during audio playback

[koba]

[Impact]
audio card disappeared after suspend device during audio playback

[Fix]
Set trigger order for FE DAI links to SND_SOC_DPCM_TRIGGER_POST to trigger the BE DAI's before the FE DAI's. This prevents the xruns seen on playback pipelines using the link DMA.

[test]
With the patch, machine could be suspended successfully and
ALSA device still presents after leave suspension.

[Regression Potential]
Low. If some DSPs need the reverse order(FE->BE), we may get the same error.
