    dtc: Convert "name" property checking to new infrastructure
    
    This patch removes the old-style checking code for the "name" property
    - i.e. verifying that the "name" property, if present, matches the
    node name.  It replaces it with a pair of more-or-less equivalent
    checks in the new checking framework.
    
    This also promotes this check to a "structural" check, or at least an
    error-rather-than-warning test, since the structural/semantic
    distinction doesn't really apply in the new framework.
    
    A testcase for the check is also added.
