RTC: Cleanup rtc_class_ops->update_irq_enable()
Now that the generic code handles UIE mode irqs via periodic
alarm interrupts, no one calls the
rtc_class_ops->update_irq_enable() method anymore.
This patch removes the driver hooks and implementations of
update_irq_enable if no one else is calling it.
