MLK-23970: ASoC: fsl_dsp: workaround for no reset controller
On imx8mp, there is no dedicated reset controller for DSP and
there is no dedicated power domain for DSP.
The power of DSP is bound with audiomix, so we need to check
the DSP status for judging the audiomix is reset or not.
We use the PID register for status check, after reset, it will
be set to zero, when DSP is used we set it to 1.
