  1. zephyr: use k_smp_cpu_start/_resume for secondary core power up 

    This changes the secondary core power up routine to use the newly
introduced k_smp_cpu_start() and k_smp_cpu_resume(). This removes
the need to mirror part of the SMP start up code from Zephyr, and
no longer need to call into Zephyr private kernel code.

West update includes :

eefaeee061c8 kernel: smp: introduce k_smp_cpu_resume
042cb6ac4e00 soc: intel_adsp: enable DfTTS-based time stamping
             on ACE platforms

  2. chain_dma: workaround for failed DMA stop on pause/stop 

    Starting with Zephyr commit e021ccfc745221c6 ("drivers: dma:
intel-adsp-hda: add delay to stop host dma"), the pause-resume
sof-test cases started failing on Intel cAVS2.5 platforms.

Add a delay loop around DMA stop code in chain DMA to workaround
the issue while a proper fix is under investigation. This allows
to resume integration of newer Zephyr versions to SOF and ensure
we detect any new regressions in time.
