[PULL REQUEST] i2c for 4.10

[Wolfram Sang]

Linus,

here is the first pull request from I2C for 4.10, including:

* the first series of making i2c_device_id optional instead of mandatory
  (in favor of alternatives like of_device_id). This involves adding a
  new probe callback (probe_new) which removes some peculiarities I2C had
  for a long time now. The new probe is matching the other subsystems
  now and the old one will be removed once all users are converted. It
  is expected to take a while but there is ongoing interest in that.
* SMBus Host Notify introduced 4.9 got refactored. They are now using
  interrupts instead of the alert callback which solves multiple issues.
* new drivers for iMX LowPower I2C, Mellanox CPLD and its I2C mux
* significant refactoring for bcm2835 driver
* usual set of driver updates and improvements

Thanks,

   Wolfram
