This adds basic NO_IDLE_HZ support to the SH timer API so timers
are able to wire it up. Taken from the ARM version, as it fit in
to our API with very few changes needed.

At the moment we wrap GENERIC_TIME around our existing timer API.
As boards start providing their own clocksources, they're able to
select GENERIC_TIME accordingly and optimize out most of the timer
API.
Once the current timers have been reworked as proper clocksource
drivers, the rest of the place holders for the timer API can go
away and we can flip on GENERIC_TIME unconditionally.

This adds some simple PM stubs and the basic APM interfaces,
primarily for use by hp6xx, where the existing userland
expects it.

This builds on some of the clock framework code to support a simple system
timer interface.
