rtc: pfc8563: fix uninitialized variable warning
Gcc is unable to prove that alm_pending is always initialized
when it is used, so it prints a harmless warning:
drivers/rtc/rtc-pcf8563.c: In function 'pcf8563_probe':
drivers/rtc/rtc-pcf8563.c:449:5: warning: 'alm_pending' may be used uninitialized in this function [-Wmaybe-uninitialized]
This uses the same conditional expression that is used inside of
the pcf8563_get_alarm_mode() function, to help gcc figure it out
and shut up that warning, and make the ARM defconfigs build again
with no warnings.
