clockevents/drivers/metag_generic: Migrate to new 'set-state' interface 

Migrate metag_generic 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.

We weren't doing anything in the ->set_mode() callback. Even the WARN()
for periodic or unused modes isn't required anymore as the core is
taking care of that now. So, this patch doesn't provide any set-state
callbacks.
