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).
