Added I2C SMBus driver and device tree bindings documentation.
Changes since v3:
Device bindings documentation:
- Re-order property descriptions.
- Remove useless register addresses from the resource
description.
- Mention default clock-frequency value.
- Fix format issues; remove spaces.
- Omit "aliases" from Example section.
- Rename device instance node in Example section.

+Device tree configuration for the Mellanox I2C SMBus on BlueField SoCs
+
+Required Properties:
+- compatible : should be "mellanox,i2c-mlxbf1" or "mellanox,i2c-mlxbf2".
+
+- reg : address offset and length of the device registers. The
+ registers consist of the following set of resources:
+ 1) Smbus block registers.
+ 2) Cause master registers.
+ 3) Cause slave registers.
+
+- interrupts : interrupt number.
+
+Optional Properties:
+
+- clock-frequency : bus frequency used to configure timing registers;
+ allowed values are 100000, 400000 and 1000000;
+ those are expressed in Hz. Default is 100000.
+
+Example:
+
+i2c@2804000 {
+ compatible = "mellanox,i2c-mlxbf1";
+ reg = <0x02804000 0x800>,
+ <0x02801200 0x020>,
+ <0x02801260 0x020>;
+ interrupts = <57>;
+ clock-frequency = <100000>;
+};
