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.

V2->V3: Was trying to be too smart by only fixing includes needed.
Took a more general approach this time, converting of_i2c.h
to i2c.h in case i2c.h was not already there. Otherwise
remove it. Improved my build scripts and no build failures,
no complaints from buildbot as well.
