Description
【前提条件】
None
【测试步骤】
1、通过稳压电源给设备供电开机
2、使用稳压电源使设备过压保护关机
3、短时间内恢复正常电压12
【预期结果】
3. 设备自动开机
【实际结果】
3. 设备不能正常开机，需要重新上下电才能开机

当前代码在过压/欠压时，存在以下情况：
1.过压/欠压持续时间小于2s，不会通知MPU关机。（正常）
2.过压/欠压持续时间大于2s后，会通知MPU关机，且持续时间大于7s后，执行过/欠压保护重置IO状态，执行断电重启动作。（正常）
3.过压/欠压持续时间大于2s小于7s时，即在这段时间内恢复为正常电压，会出现该BUG情况。因只通知了关机，但未执行过/欠压保护重置IO状态。导致MPU在重启时无法正常重启。（异常）
修改：
只要MCU通知MPU关机后（过/欠压状态持续时间大于2s），等待MPU正常关机，在7s后都会执行执行过/欠压保护重置IO状态。
修改后暂未复现该BUG。

今天连接屏幕测试未复现，
代码修改已提交https://dev.thundercomm.com/gerrit/c/Pre_figure/mcu/+/194981
待VB出包后，可验证该问题。

VB包已出，可验证，/Pre_figure/VerifyBuild/Pre_figure_turbox-c2130c-la1.1-qssi12-dev/20230420/202304202042-3368

vb版本验证结果如下：
1. 过压17V 2s后关机，快速（1-2s）回到12V，设备开机 压测：30
2. 过压17V 2s后关机，快速回到12V 2-7s，设备启动时再次拉升17V 稳定7s以上，再下降12V
循环20次，最终可以正常开机
等正式版本再次验证
