alpha/time: Migrate to new 'set-state' interface
alpha/time: Migrate to new 'set-state' interface

Migrate alpha 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.

rtc clockevent device wasn't doing anything in set-mode and so its
set-state callbacks aren't implemented.
