ARM: dts: overo: Create a file for common Gumstix peripherals
Gumstix expansion boards share a couple of peripherals: - uart3 is used for the console - AT24C01 EEPROM on i2c3 Use this file for overo-tobi. Signed-off-by: Florian Vaussard <florian.vaussard@epfl.ch> Signed-off-by: Tony Lindgren <tony@atomide.com>
