  1. intel_adsp/ace: power: Restore PS after power gate 

    We are arbitrarily setting a value to PS after power gates and
losing valid information like OWB, CALLINC and INTLEVEL.

We need to properly save/restore them to avoid possible wrong behavior.

  2. intel_adsp/cavs: power: Fix INTLEVEL value 

    In pm_state_set we can't just call k_cpu_idle() because
this will clear out PS.INTLEVEL. Use k_cpu_atomic_idle instead
since Zephyr's expect interruptions to be locked after pm_state_set.
