From: Viresh Kumar <viresh.kumar@linaro.org>
Migrate arm_arch_timer driver to the new 'set-state' interface provided
by the 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.
