Populate the ina3221 current/voltage monitor sensors for the various
Tegra234 boards. The ina3221 sensors are located on the Tegra234 module
boards. The sensor configuration for the Jetson AGX Orin and NVIDIA
IGX Orin boards are the same and the sensor configuration for Jetson Orin
NX and Jetson Orin Nano are the same.
