    net: dsa: mt7530: fix trapping frames on non-MT7621 SoC MT7530 switch
    
    [ Upstream commit 4ae90f90e4909e3014e2dc6a0627964617a7b824 ]
    
    All MT7530 switch IP variants share the MT7530_MFC register, but the
    current driver only writes it for the switch variant that is integrated in
    the MT7621 SoC. Modify the code to include all MT7530 derivatives.
