There was some talk about this on the mailing list where TDX and SEV may
need to be differentiated, so we wanted to reserve a range of values per
technology. I guess I can remove them until they are actually needed.

In TDX also we have similar requirements and we need some flags for
TDX specific checks. So I think it is fine to leave some space for vendor
flags.
