clocksource/drivers/timer-sun4i: Add CLOCK_EVT_FEAT_DYNIRQ
Add CLOCK_EVT_FEAT_DYNIRQ to allow the IRQ could be runtime set affinity
to the cores that needs wake up, otherwise saying core0 has to send
IPI to wakeup core1. With CLOCK_EVT_FEAT_DYNIRQ set, when broadcast
timer could wake up the cores, IPI is not needed.
After enabling this feature, especially the scene where cpuidle is
enabled can benefit.
