MIPS: cevt-ds1287: Migrate to new 'set-state' interface
Migrate cevt-ds1287 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.
