rtc: rv3028: Use IRQ flags obtained from device tree if available

Browse Source 
Make the interrupt pin of the RV3028 usable with GPIO controllers
without level type IRQs support, such as the TI Davinci GPIO controller.

Therefore, allow the IRQ type to be passed from the device tree if
available.

Based on commit d4785b4634 ("rtc: pcf2127: use IRQ flags obtained from device tree if available")
