Yongbae Park 1e529ecd36 clockevents: sun5i: Fix setup_irq init sequence
commit 1096be084a upstream.

The interrupt is enabled before the handler is set. Even this bug
did not appear, it is potentially dangerous as it can lead to a
NULL pointer dereference.

Fix the error by enabling the interrupt after
clockevents_config_and_register() is called.
