设备持续做power cycle的操作，跑到105圈的时候，发现PCIe5 Chip 1的温度传感器无读值
PCIe5 设备为Atlas 300 IDUO的NPU卡
通过查看文件vpd\vendor\Huawei\Gpu\14140130_19e5d500_02000110.sr，NPU的CHIP温度传感器定义，温度从NPUCard_1.Core1TemperatureCelsius获取。

尝试修改PCIe5 Chip1 的ReadingDisplay的值为80，PCIe5 Chip1 Temp传感器的值在WEB上还是无显示。
尝试修改PCIe5 Chip0 的ReadingDisplay的值为80，PCIe5 Chip0 Temp传感器的值在WEB上可以更新。
