clocksource/drivers: Set clockevent device cpumask to cpu_possible_mask
Currently, quite a few clockevent devices have cpumask set to cpu_all_mask which should be fine. However, cpu_possible_mask is more accurate and if there are any other clockevent devices in the system which have cpumask set to cpu_possible_mask, then having cpu_all_mask may result in issues (mostly boot hang with forever loops in clockevents_notify_released). So, lets replace all the clockevent device cpu_all_mask to cpu_possible_mask in order to prevent above mentioned possible issue.
