Add I2C driver framework

Browse Source 
This I2C driver framework has some major differences compared to libi2c.

* It is compatible to the Linux I2C user-space API.

* It uses generic IMFS nodes and thus reduces the levels of indirection.

* The drivers don't have to mess around with minor numbers to get their
  state information.

* No arbitrary bus controller model is assumed.  The main task of an I2C
  bus controller driver is to process I2C messages.  How this is done is
  private to the driver.

* Scatter/gather operations are supported (I2C_M_NOSTART).
