While the SPI was recording using the DAI "rt5514-dsp-cpu-dai", the event "DAPM Pre" would be manipulated even the DAPM widgets were not connected, and it also would power off the DSP that cause the DSP buffered data lost. So the auto disable DSP function should move to the set_bias_level() function to make sure that it is only manipulated by the DAPM widgets are connected.
