Oh, and how is the ordering ensured in this case? We need to set the
dynamic PCD at runtime, but obviously before AcpiTableDxe gets a
chance to load. If the only way to achieve this is another NULL class
library, then this is not much of an improvement. Or could we detect
the table-loader node from PEI as well?
