The hw->formats may be set by snd_dmaengine_pcm_refine_runtime_hwparams() in component's startup()/open(), but soc_pcm_hw_init() will init hw->formats in dpcm_runtime_setup_fe() after component's startup()/open(), which causes the valuable hw->formats to be cleared.
So need to store the hw->formats before initialization, then restore it after initialization.
