clockevents/drivers/vt8500: Migrate to new 'set-state' interface
Migrate vt8500 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.
