rtc: pcf8563: Fix interrupt trigger method

Browse source 
The PCF8563 datasheet says the interrupt line is active low and stays
active until the events are cleared, i.e. a level trigger interrupt.

Fix the flags used to request the interrupt.

Fixes: ede3e9d47c ("drivers/rtc/rtc-pcf8563.c: add alarm support")
