[PULL REQUEST] i2c for 4.8

[Wolfram Sang]

Linus,

here is the I2C pull request for 4.8:

* the core and i801 driver gained support for SMBus Host Notify
* core support for more than one address in DT
* i2c_add_adapter() has now better error messages. We can remove all
  error messages from drivers calling it as a next step.
* bigger updates to rk3x driver to support rk3399 SoC
* the at24 eeprom driver got refactored and can now read special variants with
  unique serials or fixed MAC addresses.

The rest is regular driver updates and bugfixes. Please pull.

Thanks,

   Wolfram
