Ah, its because the enum is shared between two different use-cases. The
one is the clockevent driver for the clock_event_device::set_mode()
call, and one is the clockevent core call: clockevent_set_mode().

The previous patch changed the driver interface, but retained the
sharing of the enum across both interfaces.

Maybe we should break that enum into two; one for devices and one for
the core interface and avoid the problem that way.
