rtc: xgene: mark PM functions as __maybe_unused
The new xgene_rtc_alarm_irq_enabled() function is only accessed
from PM code, which is inside of an #ifdef; this causes a harmless
build warning when CONFIG_PM is disabled:
drivers/rtc/rtc-xgene.c:108:12: error: 'xgene_rtc_alarm_irq_enabled' defined but not used [-Werror=unused-function]
Just remove the #ifdef and use __maybe_unused annotations instead,
to make the code more robust here.
Fixes: d0bcd82b1379 ("rtc: xgene: Fix suspend/resume")
