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.
