MLK-18245-1: ASoC: fsl_dsp: remove the explicit power enablement

Browse Source 
The driver don't need to explicit enable the power domain, which
can be done by runtime power management, when the power domain tree
defined in device tree.
in this case, the MU initialization can be moved to runtime pm function.
