x86/hyperv: Add an interface to do nested hypercalls
According to TLFS, in order to communicate to L0 hypervisor there needs
to be an additional bit set in the control register. This communication
is required to perform privileged instructions which can only be
performed by L0 hypervisor. An example of that could be setting up the
VMBus infrastructure.
