KVM: PPC: Add get_pvinfo interface to query hypercall instructions
We need to tell the guest the opcodes that make up a hypercall through interfaces that are controlled by userspace. So we need to add a call for userspace to allow it to query those opcodes so it can pass them on. This is required because the hypercall opcodes can change based on the hypervisor conditions. If we're running in hardware accelerated hypervisor mode, a hypercall looks different from when we're running without hardware acceleration.
