The bindings required interrupts for all SoCs but actually only the PWM
timer clocksource (for S3C/S5P SoCs) was using them. This PWM timer
clocksource driver is not used on Exynos SoCs thus the interrupts can be
marked as optional.

Be aware that the clocksource driver supports only uniprocessor systems.
