[PULL REQUEST] i2c for 4.3

[Wolfram Sang]

Linus,

here is the pull request for i2c. Features:

* new drivers: Renesas EMEV2, register based MUX, NXP LPC2xxx
* core: scans DT and assigns wakeup interrupts. no driver changes needed.
* core: some refcouting issues fixed and better API for that
* core: new helper function for best effort block read emulation
* slave framework: proper DT bindings and userspace instantiation
* some bigger work for xiic, pxa, omap drivers

And quite a number of smaller driver fixes, cleanups, improvements.

Please pull.

Thanks,

   Wolfram
