For some reason we endedup allocating sdw_stream_runtime for every cpu dai,
this has two issues.
1. we never set snd_soc_dai_set_stream for non soundwire dai, which
means there is no way that we can free this, resulting in memory leak
2. startup and shutdown callbacks can be called without
hw_params callback called. This combination results in memory leak
because machine driver sruntime array pointer is only set in hw_params
callback.
Fix this by
1. adding a helper function to get sdw_runtime for substream
which can be used by shutdown callback to get hold of sruntime to free.
2. only allocate sdw_runtime for soundwire dais.
Fixes: d32bac9cb09c ("ASoC: qcom: Add helper for allocating Soundwire stream runtime")

remove redundant code and pointers to handle sdw_stream_runtime by
making use of qcom_snd_sdw_get_stream(). This removes need of machine
specific shutdown and hw_params sdw callbacks and also need to store
sdw_stream_runtime pointers in machine drivers.
