audio card disappeared after suspend device during audio playback Edit
[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.

With the patch, mantis n5 14 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.
