These happen at v3.14. But, maybe because of branch merge conflict or something similar happen then, soc_pcm_close() still has old settings (care only dai->rate, doesn't care dai->channels/sample_bits). This is 100% duplicated operation. This patch removes soc_pcm_close() side operation which supposed to already moved to soc_pcm_hw_free().

At first, soc_pcm_open() operation order is 1) CPU DAI startup 2) Component open 3) Codec DAI startup 4) rtd startup But here, 2) will call try_module_get() if component has module_get_upon_open flags. This means 1) CPU DAI startup will be operated *before* its module was loaded. DAI should be called *after* Component. Second, soc_pcm_close() operation order is 1) CPU DAI shutdown 2) Codec DAI shutdown 3) rtd shutdown 4) Component close soc_pcm_open() and soc_pcm_close() are paired function, but, its operation order is unbalance. This patch tidyup soc_pcm_open() order to Component -> rtd -> DAI.
