Alexander Kochetkov 97eca46d52 clocksource/arm_global_timer: reconfigure clockevents after cpufreq change 
After a cpufreq transition, update the clockevent's frequency
by fetching the new clock rate from the clock framework and
reprogram the next clock event.

The clock supplying the arm-global-timer on the rk3188 is coming
from the the cpu clock itself and thus changes its rate everytime
cpufreq adjusts the cpu frequency.

Found by code review, real impact not known. Assume what actual
HZ value will be different from expected on platforms using
arm-global-timer as clockevent.

The patch is port of commit 4fd7f9b128 ("ARM: 7212/1: smp_twd:
reconfigure clockevents after cpufreq change") and
commit 2b25d9f64b ("ARM: 7535/1: Reprogram smp_twd based on
new common clk framework notifiers").
