ASoC: soc-pcm: add a flag to reverse the stop sequence
On stream stop, currently CPU DAI stop sequence invoked first
followed by DMA. For Few platforms, it is required to stop the
DMA first before stopping CPU DAI.
Introduced new flag in dai_link structure for reordering stop sequence.
Based on flag check, ASoC core will re-order the stop sequence.
