arm64: tegra: Add ID EEPROM for Jetson TX1 Developer Kit
There is an ID EEPROM on the Jetson TX1 carrier board, part of the Jetson TX1 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. Acked-by: Jon Hunter <jonathanh@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
