It is conceptually wrong for this information to exist in the hypervisor in the first place. Only the toolstack is capable of correctly reasoning about the non-migrateability of guests. This hypercall has only ever existed to control the visibility of the Invariant TSC flag to the guest. Now that we have properly disentanged that and moved ITSC into the guests CPUID policy, delete this hypercall. Furthermore, this fixes a corner case where Xen would override the toolstacks choice of ITSC for a xenstore stubdomain. That said, init-xenstore-domain doesn't currently ask for ITSC, and MiniOS doesn't know what ITSC is either, so nothing actually changes in practice.
