[PULL REQUEST] i2c for 4.6

[Wolfram Sang]

Linus,

here is the pull request for I2C. Mostly usual driver updates and
improvements. The changelog should give an idea. Standing out is the
i2c-qup driver with lots of new capabilities and we also have now an
i2c-demuxer.

I'd especially like to welcome Peter Rosin as the i2c-mux maintainer. He
has an interesting series for muxes in the queue and agreed to look
after this part of the subsystem. Thank you, Peter, and welcome again!

The octeon changes were applied pretty recently before the merge window.
I am aware. They are the first (and relatively simple) patches of a
larger overhaul to this driver. In case something goes wrong with them,
they are easy to fix (or revert). The advantage I see is that they are
out of the way, and I can concentrate on the next block of patches. I
really would like to apply the overhaul in smaller batches to avoid
regressions. And waiting a cycle for the introductory patches seemed too
much of a delay for me.

Please pull.

Thanks,

   Wolfram
