There is no point in having an extra type for extra confusion. u64 is

Migrate EP93xx 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.

When refactoring the EP93xx timer some of the documentation
git out of date. Update it.

If we switch clock events to timer 3 we will have more bits to
use and can sleep longer when using NO_HZ.

The timer has no business using __raw accessors, in this case
the readl/writel makes perfect sense as the changes really need
to hit these registers before we continue.

This switches the EP93xx to use GENERIC_CLOCKEVENTS and
CLKSRC_MMIO. Also implements a sched_clock() hook.
Tested on the SIM.ONE. Use only oneshot events.

This breaks the timer code out of the core file in preparation
for refactoring.
