platform/x86: intel-vbtn: match power button on press rather than release
This fixes a problem where the system gets stuck in a loop
unable to wakeup via power button in s2idle.
The problem happens because:
- press power button:
- system emits 0xc0 (power press), event ignored
- system emits 0xc1 (power release), event processed,
emited as KEY_POWER
- set wakeup_mode to true
- system goes to s2idle
- press power button
- system emits 0xc0 (power press), wakeup_mode is true,
system wakes
- system emits 0xc1 (power release), event processed,
emited as KEY_POWER
- system goes to s2idle again
To avoid this situation, process the presses (which matches what
intel-hid does too).
