ARM: dts: overo: Add LIS33DE accelerometer
The LIS33DE accelerometer is used on several Gumstix expansion boards, thus add the DT node to omap3-overo-common-peripherals.dtsi. For the boards that do not have the accelerometer (like Tobi), mark the status as disabled. Signed-off-by: Florian Vaussard <florian.vaussard@epfl.ch> Signed-off-by: Tony Lindgren <tony@atomide.com>
