platform/x86: intel_pmc_ipc: add option to build without ACPI 

Introduce 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 [1], it was necessary to
provide this option to accommodate specific use cases.
