clockevents/drivers/time-armada-370-xp: Migrate to new 'set-state' interface
Migrate time-armada-370-xp 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.
