    ar71xx: Fix switch config on Mikrotik RB450/G
    
    This patch fixes the ethernet switch initial config for Mikrotik RB450 and RB450G.
    The previous version wrongly changed the RouterStation Pro config. This one creates a specific config for the RB450G and leaves the RouterStation Pro unchanged.
