[PULL REQUEST] i2c for 3.15

[Wolfram Sang]

Linus,

here is the pull request from the i2c subsystem. It got a little delayed
because I needed to wait for a dependency to be included (b424080a9e08
reset: Add optional resets and stubs). Plus, I had some email problems.
All done now, the highlights are:

* drivers can now deprecate their use of i2c classes. That shouldn't be
  used on embedded platforms anyhow and was often blindly copy&pasted.
  This mechanism gives users time to switch away and ultimately boot
  faster once the use of classes for those drivers is gone for good.

* new drivers for QUP, Cadence, efm32

* tracepoint support for I2C and SMBus

* bigger cleanups for the mv64xxx, nomadik, and designware drivers

And the usual bugfixes, cleanups, feature additions. Most stuff has been
in linux-next for a while. Just some hot fixes and new drivers were
added a bit more recently. Please pull.

Thanks,

   Wolfram
