Some platforms are set suspend-to-idle (s2idle) as default suspend mode, and then they can't resume the system from opening the lid.

[Test Case]
1. echo s2idle | sudo tee /sys/power/mem_sleep
2. Close the lid
3. Open the lid

According a patch sent to 4.17-rc1, which was not be included before 4.15 EOL, so we cherry pick the patch to Ubuntu 4.15 kernel.


[Regression Potential]
Per commit, this change also allows Dells XPS13 9360 blacklisted by commit 71630b7a832f to use the power button for waking up from suspend-to-idle, no regression could be happened
