Pull i2c updates from Wolfram Sang:
 "For 3.14, the I2C subsystem has the following to offer:

   - new drivers for Renesas RIIC and RobotFuzz OSIF
   - driver cleanups & improvements & bugfixes

  Pretty standard stuff this time, I'd say.  There is more complex stuff
  coming up, but I didn't have the bandwidth between the years to pull
  it in for this release.  Sadly"
