The DXE and SMM versions of AcpiDebug perform the same task and are therefore mutually exclusive. Including both modules results in a duplicate ACPI table, resulting in the feature not working at all. Therefore, add a new PCD to determine which module will be included. Now, either version successfully write to the debug buffer.
