Never thought of that, but I wouldn't care. There is no good reason to
do this.

This doesn't seem to be a blocker either. For one thing, i2c
subsystem-wide changes tend to affect chip drivers more than bus
drivers. And even then, looking for drivers in 2 directories doesn't
seem much harder than looking into just one, especially when said 2
directories live next to each other.

So I see no objection to a mass move of all embedded/system i2c bus
drivers to a separate sub-directory.
