Yes, this is what I wanted to discuss. I had a felling that it is not
quite right. I think your idea with DOMCTL is better. I'll rework this
part in the following way:
if there is "optee=1" in a config file, then libxl will create DT entry
and ask hypervisor to enable access to TEE for this domain.
