config: ace: enable dynamic clock switching

Enable the dynamic clock switching feature for Intel ADSP platforms. This feature allows the DSP to adjust its clock frequency dynamically when all cores enter the idle state, reducing energy consumption while waiting for interrupts. The following Kconfig options are added to MTL and LNL configuration: - CONFIG_PM_STATE_CUSTOM_DATA: Allows setting custom data pointers for specific power states. - CONFIG_ADSP_DYNAMIC_CLOCK_SWITCHING: Enables dynamic clock switching during idle states, dependent on the availability of custom power state data. This change is part of ongoing efforts to enhance power management capabilities and improve the energy efficiency of these platforms. Signed-off-by: Tomasz Leman <tomasz.m.leman@intel.com>
