qcom: msm: event-timer: Add eventimer migration framework

Currently, all the event timers are associated to CPU0. These event
timers are not bind to any of the IRQs and always handled(hrtimer)
by CPU0. This event timers framework make sure event timers are
bound to clients IRQs and when the IRQ affinity has changed event
timer framework will make sure to move associated event timer to
a new CPU based on IRQ affinity.
