rtc: efi: switch to RTC_FEATURE_UPDATE_INTERRUPT

alexandrebelloni · alexandrebelloni · commit 1350b94c94cc · 2022-03-23T19:58:40.000+01:00
Stop using uie_unsupported and clear RTC_FEATURE_UPDATE_INTERRUPT instead. Also the driver doesn't supports UIE because it doesn't handle interrupts so set RTC_FEATURE_ALARM_WAKEUP_ONLY,.
