rtc: pcf8563: Fix interrupt trigger method
[ Upstream commit 65f662cbf829834fa4d94190eb7691e5a9cb92d8 ]
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: ede3e9d47cca ("drivers/rtc/rtc-pcf8563.c: add alarm support")
