Add I2C SMBus driver and device tree bindings documentation.
The Mellanox BlueField is a System-on-Chip (SoC) that combines
Arm cores and ConnectX network adapter technology intended to
accelerate storage network solutions. The Mellanox BlueField
incorporates various I2C devices that are accessed using SMBus
protocol, a variant of the I2C protocol. On storage controllers,
the BlueField SoC is connected to a management controller board,
e.g., BMC via an I2C bus.
An I2C driver running on the Arm side is needed to manage the
hardware I2C controllers. The driver enables a master function
to transfer data back and forth from/to I2C devices, such as
EEPROM parts and implements a slave function to handle the BMC
controller requests.
