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.
