ARM: Make the sched_clock framework mandatory
All sched_clock() providers have been converted to the sched_clock framework, which also provides a jiffy based implementation for the platforms that do not provide a counter. It is now possible to make the sched_clock framework mandatory, effectively preventing new platforms to add new sched_clock() functions, which would be detrimental to the single zImage work.
