Would the Xen specific bits fit into Confidential Computing Platform

I don't think cc_platform_has would be correct here. Xen certainly
provides more isolation between guests and dom0, but "Confidential
Computing" is basically orthogonal to that feature.
The point of cc_platform_has is to remove all these open code checks.
If a Xen hypervisor / dom0 can't access arbitrary guest memory for
virtual I/O and we need special APIs for that it certainly false
into the scope of cc_platform_has, even if the confientiality is
rather limited.
