rtc: rv3028: Use IRQ flags obtained from device tree if available
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 d4785b46345c ("rtc: pcf2127: use IRQ flags obtained from device tree if available") Signed-off-by: Wadim Egorov <w.egorov@phytec.de> Link: https://lore.kernel.org/r/20221208133605.4193907-1-w.egorov@phytec.de Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
