452831f315 ARM: dts: imx6dl-yapp4: Enable the I2C3 bus on all board variants 
imx6dl-yapp4 Draco and Ursa boards use the I2C3 bus to control some
external devices through the /dev files.

So enable the I2C3 bus on all board variants, not just on Hydra.

764b5b5e70 ARM: dts: imx6dl-yapp4: Enable the MPR121 touchkey controller on Hydra 
Add the touch keyboard present on Hydra board. The controller
is connected only using I2C lines. The interrupt line is not
available hence we use the polling mode.
