Added I2C SMBus driver and device tree bindings documentation.
This patch set depends on ARCH_MLNX_BLUEFIELD. There is separate
effort that aims to add support for the Mellanox BlueField SoC
to the kernel tree.

Changes since v1:

1) Device bindings documentation:

   - Enumerate the device resources.
   - Edit the 'compatible' property to make it less generic.
   - Remove the 'bus' index property and replace i with a
     standard approach to read the bus identifier.
   - Get rid of the 'profile' property.
   - Use 'clock-frequency' property instead of 'bus-freq'.
   - Convert the clock frequency from KHz to Hz.
   - Remove useless examples.

2) Device driver source:

   - Update the '.compatible' field of of_device_id.
   - Update mlx_i2c_of_probe() call to extract the bus id
     from the pre-defined aliases.
   - Don't check the profile property.
   - Read the 'clock-frequency' property to get the timing
     parameters. 
   - Convert the timing configuration from KHz to Hz.
