MN10300: Make sched_clock() report time since boot
Make sched_clock() report time since boot rather than time since last
timer interrupt.
Make sched_clock() expand and scale the 32-bit TSC value running at
IOCLK speed (~33MHz) to a 64-bit nanosecond counter, using cnt32_to_63()
acquired from the ARM arch and without using slow DIVU instructions
every call.
