Noooo....

First of all, this commit doesn't touch the S3, so you probably
mean S4.

Secondary this commit just enables the wakeup devices in S4 mode.

It is just like removing the S4 altogether, it will also 'fix'
all the systems that don't suspend to disk properly.

At maximum there should be an option to do a mixed suspend
Enter using the firmware, but powerdown devices instead of suspend

Something like "platform_shutdown"
