This patch adds nodes required to enable 4 i2c buses on the board which
are connected to various sensors and eeprom.


I would like for the pinconf for these blocks to be in this patch (and
file) to make it clear how they are configured and where to change them.

When I started adding this I had same opinion, I will do that in next release.

thanks,
