[DNM] intel_adsp: ace: dynamic clock switching

[tmleman]

This pull request introduces a series of enhancements to the power management capabilities of the Intel ADSP platforms. The changes include the implementation of dynamic clock switching, which allows the DSP to adjust its clock frequency based on the idle state of the cores, thereby reducing power consumption during idle periods.

No, this change is not intended to replace it. It's more of an extension. Thanks for asking; I've added this PR as a dependency.
