ASoC: add new trigger ordering method
Current ASoC is assuming that trigger starting order is Link -> Component -> DAI as default, and its reverse order for stopping. But some Driver / Card want to reorder it for some reasons. We have such flags, but is unbalance like below. struct snd_soc_component_driver :: start_dma_last struct snd_soc_dai_link :: stop_dma_first We want to have more flexible, and more generic method. This patch adds new snd_soc_trigger_order for start/stop at component / DAI-link.
