[PATCH] ARM: dts: rockchip: add i2c-bus subnode to edp

Add an empty 'i2c-bus' subnode to the edp node just so that the I2C core
doesn't attemp to parse the 'ports' subnode as containing i2c devices.

This is to avoid spurious failure messages such as:

i2c i2c-6: of_i2c: modalias failure on /dp at ff970000/ports
