Changes since v1 (no emails related to this series since last week):
- accumulate tags (both were added because it seems like the discussion
ended in agreement to keep adding compatible strings to the driver)
This adds the compatible string for the Qualcomm Snapdragon 670's SMMU. The
SMMU is necessary for GENI I2C, included in initial bringup because it
doesn't need non-trivial patches except for patches conventionally added
before the initial device tree (global clock controller and pinctrl).

The Snapdragon 670 needs the IOMMU for GENI I2C. Add a compatible string in
the documentation to represent its support.
