x86/lguest/timer: Migrate to new set-state interface Migrate lguest driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED. We weren't doing anything while switching modes other than in shutdown mode and so those are not implemented.
