rtc: ds1307: Use irq when available for wakeup-source device
With commit 8bc2a40730ec ("rtc: ds1307: add support for the DT property 'wakeup-source'") we lost the ability for rtc irq functionality for devices that are actually hooked on a real IRQ line and have capability to wakeup as well. This is not an expected behavior. So, instead of just not requesting IRQ, skip the IRQ requirement only if interrupts are not defined for the device.
