Migrate em_sti 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.
NOTE: This also drops a special check:
if (old_mode == CLOCK_EVT_MODE_ONESHOT)
em_sti_stop(p, USER_CLOCKEVENT);
as it doesn't look like that important. This driver only supports
ONESHOT and we can only move only to SHUTDOWN from ONESHOT and.
Also on second call (on shutdown), em_sti_stop() would return without
disabling the device again.
