[ Upstream commit 500d0aa918a2ea6bb918fee8adcf27dc2912bcd1 ]
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.
