The ODROID C2 has 2 I2C buses, so enable both of them.

Thanks for the change, but this I2C bus is on the 40-pin header,
until we have a way to add support for HATs/CAPEs/<whatever hooks on the header>
upstream, we prefer not enabling any functions on these pins by default.

You can, if you want add support for most functions, but "disabled" with a
proper description of pins used by these functions.

You can also maintain a set of overlay files like it's done for the
libretech-cc boards https://github.com/libre-computer-project/libretech-overlays/tree/for-4.13.y/overlays
and use them with the Armbian mainline based latest image for example.

Neil
