arm64: dts: rockchip: Enable i2c2 on Orange Pi 3B

Browse Source 
Enable the "i2c2" bus on header pins 3 (I2C_SDA_M1)
and 5 (I2C2_SCL_M1) of the Orange Pi 3B board.

As documented on http://www.orangepi.org/img/pi3b/0719-pi3b-19.png,
such pins are the only ones offering I2C functionality
without conflicting with other SoC blocks.
