    I2C of helpers used to live in of_i2c.c but experience (from SPI) shows
    that it is much cleaner to have this in the core. This also removes a
    circular dependency between the helpers and the core, and so we can
    finally register child nodes in the core instead of doing this manually
    in each driver. So, fix the drivers and documentation, too.
