[PATCH v5 1/3] dt-bindings: Add vendor prefix for Caninos Loucos

[Matheus Castello]

The Caninos Loucos Program develops Single Board Computers with an open
structure. The Program wants to form a community of developers to use
IoT technologies and disseminate the learning of embedded systems in
Brazil.

It is an initiative of the Technological Integrated Systems Laboratory
(LSI-TEC) with the support of Polytechnic School of the University of
São Paulo (Poli-USP) and Jon "Maddog" Hall.

This enum still strikes me as wrong, it means either-or. (Was planning 
to look into it myself, but no time yet...) caninos,labrador-v2 should 
be a const one level down: board, SoM, SoC from most specific to most 
generic. Compare Guitar below.
