There is an ID EEPROM on the Jetson TX2 carrier board, part of the
Jetson TX2 Developer Kit, that exposes information that can be used to
identify the carrier board. Add the device tree node so that operating
systems can access this EEPROM.

There is an ID EEPROM in the Jetson TX1 module that stores various bits
of information to indentify the module. Add the device tree node so that
operating systems can access this EEPROM.
