No, we can't. The GUIDs are required as part of the EFI FMP spec. We 
currently hardcode these GUIDs per-board (meaning if a vendor productize 
some board they need to make source modifications to replace the GUIDs). 
This series generates those GUIDs deterministically at runtime so we 
don't need to maintain a big list.
