dropped because viot was wrong.
Pls rebase fix up and repost.
Apropos I still think we should split up DSDT to several
SSDTs, in a way that multiple tests share some SSDTs.
This way it will be more common than a change only affects one table
and it's easier to merge things.
For example, how about moving CXL things to an SSDT?
