clocksource: sun5i: Fix cpufreq interaction with sched_clockclockevents/4.0-rc5
The sched_clock we use on some system is this timer, and since we
started using cpufreq, the cpu clock (that is one of the timer's clock
indirect parent) now changes, along with the actual sched_clock rate.
We can safely remove the sched_clock on those systems, since we have
other reliable sched_clock in the system.
