power: reset: power key detection only when power off
1. In power off flow:
- detect power key is really released
- execute acpm_prepare_reboot
- AOSP send SMC to TF-A to do real power off action.
2. In cold reboot flow:
- skip power key detection
- execute acpm_prepare_reboot
- AOSP send SMC to TF-A to do real cold reboot action
