Bug description:
[Impact]
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
[Fix]
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.

71630b7a832f to use the power button for waking up from suspend-to-idle, no
regression could be happened
