Migrate cevt-4k driver to the new 'set-state' interface provided by

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. So, this patch
doesn't provide any set-state callbacks.
The code in __clockevents_switch_state() looks like it's going to oops as
you're not implementing set_state_oneshot()...
In fact, clockevents_sanity_check() should return -EINVAL in this case,
and so the kernel crash even earlier, duyr to BUG_ON() in
clockevents_register_device().
tglx has turned my attention the pre-requisite patch, and I have finally
found it in the archives. I'm now OK with the patches I considered broken.
