From: Alexander Kochetkov <al.kochet at gmail.com>
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.
