CONFIG_SMP_BOOT_DELAY was removed in Zephyr (commit 7a72151634e8 "kernel: smp: replace SMP_BOOT_DELAY with per-CPU devicetree deferral") in favor of the per-CPU 'zephyr,deferred-start' devicetree property. SOF relied on CONFIG_SMP_BOOT_DELAY=y (default y if SMP) so that no secondary DSP core was started at kernel boot; the cores are brought up on demand by SOF/host power management. Add per-board overlays marking every secondary core (cpu1..cpuN-1) with 'zephyr,deferred-start' to keep that behavior. The boot core (cpu0) is unaffected by the property.

Pull request overview
Updates the Zephyr revision pinned in this repository’s west.yml manifest and adds application-local DeviceTree overlays for Intel ADSP multi-core boards so secondary DSP cores use deferred start (on-demand) behavior after upstream Zephyr DTS/default changes.
Changes:
- Bump the Zephyr project
revisioninwest.ymlto a newer commit. - Add per-board
.overlayfiles underapp/boards/to mark secondary CPU nodes withzephyr,deferred-startfor Intel ADSP targets.

Do we need to cherry-pick for v2.15 ?

Seems fuzzer broke with the Zephyr update. @tmleman any idea what happens here? |

Zephyr update plus addition of DTS overlay for Intel multicore targets (to match these definitions getting dropped in Zephyr upstream).
