net: dsa: mt7530: fix trapping frames on non-MT7621 SoC MT7530 switch

Browse Source 
[ 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.

Fixes: b8f126a8d5 ("net-next: dsa: add dsa support for Mediatek MT7530 switch")
