Populate the ina219 and ina3221 power-sensors for the various Tegra234
boards. These sensors are located on the Tegra234 module boards and the
configuration of some sensors is common across the different Tegra234
modules. Therefore, add any common sensor configurations to appropriate
device tree source file so it can be re-used across modules.
