clocksource and shed_clock provided by arm-global-timer is quite unstable, because their rate depends on cpu frequency. So disable arm-global-timer and use clocksource and sched_clock from rockchip_timer. It is impossible get stable clocksource having rockchip_timer and arm-global-timer enabled at the same time. Because arm-global-timer looks like a better candidate for the kernel: it has higher frequency and rating. Disabling arm-global-timer doesn't leave kernel without clockevents as there is another clockevent provider (smp-twd).
