rtc: pcf2127: use IRQ flags obtained from device tree if available

Browse source

If the interrupt pin of the PCF2127 is routed to the input of a GPIO
expander using the pca953x driver, the later will only accept an IRQ
of type IRQ_TYPE_EDGE_FALLING or IRQ_TYPE_EDGE_RISING, and the IRQ
request will fail.

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