RTC operation not permitted causes suspend/suspend_advanced_auto failed sometime

[baconYao]

Bug Description

I found the suspend failed sometimes because of "rtcwake: /dev/rtc0: unable to find device: Operation not permitted".

This problem was observed before, See Checkbox issue: #857

At that moment, This problem could reproduced easily on G700 UC22 image. And there was a PR to fix this issue: #979

However, I can still run into this problem sometime, not 100% on G1200-evk
