clocksource/drivers/arm_global_timer: Fix maximum prescaler value 



The prescaler in the "Global Timer Control Register bit assignments" is
documented to use bits [15:8], which means that the maximum prescaler
register value is 0xff.

Fixes: 171b45a4 ("clocksource/drivers/arm_global_timer: Implement rate compensation whenever source clock changes")
