ARM: ensure all sched_clock() implementations are notrace marked
ftrace requires sched_clock() to be notrace. Ensure that all
implementations are so marked. Also make sure that they include
linux/sched.h
Also ensure OMAP clocksource read functions are marked notrace as
they're used for sched_clock() too.
