[PATCH v3 2/5] dt-bindings: media: camss: Add qcom,sdm670-camss

[Richard Acayan <mailingradian@gmail.com>]

As found in the Pixel 3a, the Snapdragon 670 has a camera subsystem with
3 CSIDs and 3 VFEs (including 1 VFE lite). Add this camera subsystem to
the bindings.

Adapted from SC8280XP camera subsystem.
