tick: SHUTDOWN event-dev if no events are required for KTIME_MAX
When expires is set to KTIME_MAX in tick_program_event(), we are sure that there
are no events enqueued for a very long time and so there is no point keeping
event device running. We will get interrupted without any work to do many a
times, for example when timer's counter overflows.
So, its better to SHUTDOWN the event device then and restart it ones we get a
request for next event. For implementing this a new field 'last_mode' is added
to 'struct clock_event_device' to keep track of last mode used.
