Currently PRM(Platform Runtime Mechanism) config option is listed along with the main ACPI (Advanced Configuration and Power Interface) option at the same level. On ARM64 platforms unlike x86, ACPI option is listed at the topmost level of configuration menu. It is rather very confusing to see PRM option also listed along with ACPI in the topmost level. Move the same under ACPI config option. No functional change, just changes the level of visibility of this option under the configuration menu.
