boards: ace: power: disable unused asynchronous runtime PM

[tmleman]

This patch removes the CONFIG_PM_DEVICE_RUNTIME_ASYNC configuration from the Intel ADSP board files, including ACE15 MTPM, ACE20 LNL, ACE30 PTL, ACE30 WCL ACE40 NVL and ACE40 NVLS.

The asynchronous runtime power management feature is not utilized by any device drivers in our project, rendering it unnecessary. By excluding this configuration, we prevent the compilation of dead code related to power management, optimizing the build process and reducing potential overhead.

LGTM, @tmleman do we need to remove the dead code from SOF or is it in Zephyr ?

[lyakh]

@tmleman is this because we never use pm_device_runtime_put_async()?

Yes.

Pull Request Overview

This PR disables unused asynchronous runtime power management across Intel ADSP board configurations to optimize build size and prevent compilation of dead code. The change systematically adds CONFIG_PM_DEVICE_RUNTIME_ASYNC=n to all Intel ADSP ACE board configuration files since no device drivers in the project utilize this feature.

• Adds explicit disabling of asynchronous runtime PM configuration
• Targets all Intel ADSP ACE board variants (ACE15, ACE20, ACE30, ACE40)
• Optimizes build process by excluding unused power management code

All code is in Zephyr.

Ack, looks good! We can't disable configuration options via the defconfig system, so this setting must be done for each board file separately (so this PR is good).

[lgirdwood]

@tmleman can we remove the code too in favor of Zephyr based PM ?

@lgirdwood there's nothing to remove on the SOF side. The code is in Zephyr side. The feature is enabled by default, and we don't use it.
