google/eve: Fix keyboard backlight enable in wake from G3 

The WAK_STS bit is not set in a wake from G3, so the check for this
bit needs to only be done when checking for a wake from S3.

This change correctly enables the keyboard backlight in wake from G3
and only does not enable it during a wake from S3.

BUG=chrome-os-partner:58666
TEST=Use Refresh+Power to issue hard reset and ensure that the keyboard
backlight turns on like it does when waking from S5.  Also force enter
hibernate with Alt+VolumeUp+H and then power back up and ensure that
the keyboard backlight is enabled when booting.
