    automation/eclair: add deviation of MISRA C:2012 Rule 14.4
    
    Update ECLAIR configuration to take into account the deviations
    agreed during MISRA meetings.
    
    Amend an existing entry of Rule 14.4 in deviations-rst:
    it is not a project-wide deviation.
    
    Tag Rule 14.4 as clean for arm.
