Add a series of unit tests which try to cover somewhat systematically
the possible inputs and what we finally get at the exit
of the Binding constructor.
Running the assumption that any (valid) YAML binding file is
something we can make a Binding instance with:
- check which properties are defined at which level (binding,
child-binding, grandchild-binding, etc) and their specifications
once the binding is initialized
- check how including bindings are permitted to specialize
the specifications of inherited properties
- check the rules applied when overwriting a binding's description
or compatible string (at the binding, child-binding, etc, levels)
Some tests covering known issues are disabled by default:
- this permits to document these issues
- while not causing CI errors (when running the python-devicetree
unit tests)
- enabling these tests without causing errors should allow us
to consider the related issues are fixed
