boards: ace: power: disable unused asynchronous runtime PM

tmleman · tmleman · commit 6ab073a04e11 · 2025-09-26T14:31:03.000+02:00
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.
