The clocksource and the sched_clock provided by the arm_global_timer
are quite unstable because their rates depend on the cpu frequency.

On the other side, the arm_global_timer has a higher rating than the
rockchip_timer, it will be selected by default by the time framework
while we want to use the stable rockchip clocksource.

Let's disable the arm_global_timer in order to have the rockchip
clocksource selected by default.

Later on we might need to look at the rk3066 as well, as it might have the 
same issue.
