This patch introduces a configuration option that allows users to build the intel_pmc_ipc driver without ACPI support. This is useful for systems where ACPI is not available or desired. Based on the discussion from the patch: https://patchwork.kernel.org/ project/netdevbpf/patch/20250227121522.1802832-6- yong.liang.choong@xxxxxxxxxxxxxxx/#26280764, it was necessary to provide this option to accommodate specific use cases.
