[PATCH v7] ARM: dts: mvebu: Introduce a new compatible string for mv64xxx-i2c

[Gregory CLEMENT]

The mv64xxx-i2c embedded in the Armada XP have a new feature to
offload i2c transaction. This new version of the IP come also with
some errata. This lead to the introduction to a another compatible
string.

This commit updates the Device Tree binding documentation accordingly.

  Generator" by "For the Armada XP" in the examples
