As discussed in v4: I don't know if there's software relying on this or 
just a user who found these to be missing:

https://gitlab.com/qemu-project/qemu/-/issues/708

I can only say that these entries were missing, so I added them. It 
makes TPM ACPI more complete, for sure. Maybe someone else knows more if 
there's something out there that actually needs this. I'd be curious as 
well.
