meta-facebook: catalina: gpio-monitor: bind drivers when host power on
In ordet to prevent frequently new and delete i2c devices by sensor
services at runtime when host power state changes, which can cause
abnormal reading sometimes.
We move backend NIC thermal sensors to kernel dts file and add a service
to bind drivers at host first power on.
TestResults:
- Backend NIC thermal sensor bind successfully
```
