clocksource/drivers/imx-tpm: 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.
