I'm afraid I can't really help you here, sorry. That is, except for the
obvious question whether this is a regression (ie, do releases v3.17 or
earlier show something in /sys/bus/i2c/devices/?) or a configuration
issue (perhaps a distribution provided kernel does show what you want).

Hope this helps,
